Find The Measure Of The Indicated Angle To The Nearest Degree.

Answers

Answer 1

Answer:

62°

Step-by-step explanation:

We use the fact that the ratio of the sides of the triangle to the angles opposite them is given by the Law of Sines:

"In any triangle, the ratio of a side length to the sine of its opposite angle

is the same for all three sides"


[tex]\frac{a}{sinA} = \frac{b}{sinb} =\frac{c}{sinC}[/tex]

where A is the is the angle opposite side a, B the angle opposite to side b, C is the angle opposite to side c


For the given triangle we get
44/sin90 = 39/sin?

sin90 is 1 so we get 44/1 = 39/sin?

or cross-multiplying,

sin? = 39/44 = 0.886363..

? = sin⁻¹ (0.886363) = 62.42° ≈ 62° answer

Answer 2

Answer:

? ≈ 62°

Step-by-step explanation:

using the sine ratio in the right triangle

sin? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{39}{44}[/tex] , then

? = [tex]sin^{-1}[/tex] ( [tex]\frac{39}{44}[/tex] ) ≈ 62° ( to the nearest degree )

What is profit percentage?

Profit percentage is refer to "the amount of profit that has been incurred in terms of  percentage".

According to the question,

Jim buys a wardrobe for £30 which is cost price of wardrobe and he sells £44.

In order to find profit percentage we have to use formula.

Profit percentage = [tex]\frac{selling price - cost price }{cost price}[/tex] × 100

= [tex]\frac{(44-30)}{30}[/tex] × 100

= [tex]\frac{14}{30}[/tex] × 100

If sis equal to 16,c is equal to 14m and b is equal to 19m ,find the angles of 5he triangle ABC with following work steps

Answers

Answer:

Below in bold.

Step-by-step explanation:

a = 16, b = 19 and c = 14.

By the Cosine Rule:

cos A = (a^2 - b^2 - c^2) / -2bc, so:

cos A  = ( 16^2  - 19^2 - 14^2) / (-2*19*14)

             =   -301 / - 532

             =  0.565789

m < A = 55.54 degrees.

Now Using the Sine Rule:

a / sin A = b / sin B

16 / sin 55.54 = 19/sin B

sin B = 19 * sin 55.54 / 16

         = 15.666 / 16

         = 0.979125

m < B = 78.27 degrees.

Finally

m < C = 180 - 55.54 - 78.27 = 46.19 degrees.

Can somebody help me find the area of this composite shape

Answers

Alone, this shape cannot have the area solved in one step.  So, you must break it up into multiple pieces.

For this, we can break it up into a rectangle, and a right triangle.

The area formula for a rectangle is [tex]area = l*w[/tex]

The area formula for a right triangle is [tex]area = \frac{1}2} b*h[/tex]

To find the area of the rectangle, multiply 14 * 18 = 252 m^2

To find the length of the triangle, subtract 20 - 14 = 6

To find the height of the triangle, subtract 18 - 11 = 7

So, it is [tex]\frac{1}{2} 6*7[/tex] = 21 m^2

21 + 252 = 273 meters squared

In the observation of Rachel the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.

What is experimental probability?

Experimental probability of an event is the ratio of number of favorable outcome which appeared while conducting an event to the total number of outcome of that event is occurred.

Rachel found that 20 out of 48 cars that entered a parking lot were red. In this observation, the probability of a car to be red is,

[tex]P=\dfrac{20}{48}\\P=\dfrac{5}{12}[/tex]

Thus, the experimental probability that the next car that comes in is red is 5/12.

The experimental probability that the next car that comes in is not red is,

[tex]P^{-1}=1-\dfrac{5}{12}\\P^{-1}=\dfrac{12-5}{12}\\P^{-1}=\dfrac{7}{12}[/tex]

Hence, In the observation of Rachel, the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.

Answer:

∠BCD = 80°

Step-by-step explanation:

Given -

ABCD is a cyclic Quadrilateral.

∠DBC = 55°

∠BAC = 45°

To find -

∠BDC

Solution..BC is a segment and angles of same segment are equal.

=> ∠BAC = ∠BDC

=> 45° = ∠BAC { Angles of same segment BC}

In Triangle BCD

=> ∠BDC + ∠DBS + ∠BCD = 180°

=> 45° + 55° + ∠BCD = 180°

=> 100° + ∠BDC = 180°

=> ∠BDC = 180-100

=> 80° ans.

Read the passage.Ocean NoiseWhen we think about the pollution of our oceans, many of us think of oil spills that dirty the waters and harm a variety of ocean life. Or, we might think of people in boats who litter the waters with their trash. After all, how many times in the news do we hear about ships that leak dangerous chemicals into the water? What we may not realize, though, is that there is another danger that is just as harmful to ocean life as any chemical or other dangerous material: ocean noise.Many of us think of the oceans as silent places. On the contrary, they are filled with a variety of sounds. On any given day, one might hear the calls of dolphins as they swim through the waters. Whales use sounds to keep track of each other. Sea lions talk to each other to find food. Even the tiniest of shrimp make a snapping sound. There are also sounds caused by wind or rain upon the waters. Sound also plays an important role in the daily life of various ocean animals, many of which depend upon their sharp sound detection skills to survive. With increased activities by people on many of the oceans waters, the noise has increased so much that it is beginning to cause damage to the oceans as well as to the animals that live in them.Ocean noise is the term used to describe the human-made noise occurring at increasing rates in the ocean. The noise comes from many different sources: large ships, small boats with motors, and jet skis, among others. There are also underwater exploration activities such as mining, as well as radar activities of ships. One of the most harmful types of ocean noise occurs with offshore oil drilling and seismic oil explorations. Air guns are instruments that are used to determine the location of oil and natural gas beneath the sea floor. They make a sound that can damage the hearing of ocean animals.We know that sound travels faster in water than it does in air. This means that sounds in the oceans can travel for many, many miles in a short period of time. Unfortunately, sounds made by people are much louder than sounds made by ocean animals.What this means is that sounds caused by noisy engines or radar equipment used by ships can upset the everyday activities of the creatures that live in the ocean. For instance, humpback whales use songs to talk to each other. Scientists have discovered that the whales system of talking can be disturbed by loud noises. This makes it harder for the whales to find each other. The stranding of whales and dolphins has been found to increase immediately after naval sonar maneuvers. Sea lions are another type of animal that depends on sounds to communicate with other sea lions. Ocean noise can make it difficult for them to find food. Ocean noise can disturb migration routes of whales and other animals that travel to different places.However, scientists and other researchers are working hard to find a solution to this threat to marine life. Since 2003, the use of low-frequency active (LFA) sonar equipment by the United States Navy has been tightly limited because its effects have been shown to cause harm to many ocean animals. NOAA (National Oceanic and Atmospheric Administration) has released a plan to reduce ocean noise that will work better than past attempts to reduce the noise.Other people are helping as well. Some fishing companies use special equipment that makes a pinging sound to keep certain kinds of ocean life from getting caught in its fishing nets. The National Park Service completed a study that tracked tour cruise ships and made an effort to reduce the number of tours. They also tried to increase the quiet time for humpback whales by scheduling tours farther apart.Local conservation groups are also asking people to be more careful about using jet skis, motorboats, and other equipment that might disturb areas where ocean life is particularly fragile. Also, closer attention is being paid to where ships are traveling to make sure that, whenever possible, they stay away from waters where large numbers of ocean animals live.With the increase in ocean noise, measures must be taken to control or, at the very least, curb its growth.What argument does the author make in "Ocean Noise"?Marine animals contribute more to noise pollution in the ocean than humans.A reduction in noise pollution will do little to help marine life.Progress in noise reduction has been stalled by the use of sonar equipment.People must take immediate action to reduce ocean noise pollution to help marine life.
