An isosceles triangle has base angles that each measure 42°. Which equation can be used to find z, the measure of the third angle of this isosceles triangle in degrees?

84 + 2z = 180
84 + 2z = 180

42 + z = 180
42 + z = 180

84 + z = 180
84 + z = 180

42 + 2z = 180

Answers

Answer 1

Answer:

84 +z= 180

Step-by-step explanation:

Bases of an isosceles ∆ are equal so 42+42= 84

Answers

Answer:

A. No

B. No

C. Yes

Step-by-step explanation:

A and B are either below or above 180 degrees when all angles degrees are added together

C is exactly 180 degrees when all angles degrees are added together

Answer:

A. No

B. No

C. Yes

Step-by-step explanation:

A is no because the triangles do not follow the Triangle Inequality Theorem, nor do the angles add up to 180°. The Triangle Inequality Theorem states that the sum of two angles must be larger than the third side.

100 + 40 + 20 = 160° (DO NOT ADD UP TO 180°)

40 + 20 = 60 (60 IS NOT GREATER THAN THE THIRD SIDE, WHICH IS 100).

B is no because the triangle does not follow the Triangle Inequality Theorem, nor do the angles add up to  180°.

20 + 80 + 100 = 200° (DOES NOT ADD UP TO 180°)

20 + 80 = 100 (100° IS NOT GREATER THAN THE THIRD SIDE, WHICH IS 100.)

C is yes because the triangle follows the Triangle Inequality Theorem and the angles add up to 180°.

50 + 60 + 70 = 180°.

60 + 70 = 130 (130 IS GREATER THAN 50).

70 + 50 = 120 (120 IS GREATER THAN 60).

D. y = [tex]\frac{x}{10}[/tex]

Answers

Answer:

y=10/x

Step-by-step explanation:

Y=k/x

Y=2 & x=5 implies k=10

Hence, y=10/x is the desired equation of the hyperbola

...................................................................................................................................................

Answer:

The equation is  and  y = 2 , x = 5 the value of k is 10 .

Step-by-step explanation:

As given

y varies inversely with x.

Where k is the constant of proportionality .

Thus the equation for the  inverse variation .

As given

y = 2 when x = 5

Put all the values in the equation  .

k = 2 × 5

k = 10

Thus the constant of variation is 10 .

Therefore the equation is  and when y = 2 , x = 5 value of k is 10 .

Randall has a box that measures 12 inches × 9 inches × 8 inches. If Randy wants to cover the box with aluminum foil, how much foil will it take to cover the entire outside of the box?

Answers

Answer:

[tex]A=552\ inches^2[/tex]

Step-by-step explanation:

The dimensions of a box measures 12 inches × 9 inches × 8 inches.

We need to find the area of the aluminium required to cover the entire outside of the box.

We know that the surface area of the cuboidal box is given by :

[tex]A=2(lb+bh+bl)\\\\=2(12\times 9+9\times 8+8\times 12)\\\\=2\times 276\\\\=552\ inches^2[/tex]

So, the required area of the foil is equal to [tex]552\ inches^2[/tex].

The amplitude of the graphs of the sine and cosine functions is __
and the period of each is
__

Answers

The amplitude of the graphs of the sine and cosine functions is the vertical distance between the sinusoidal axis and the maximum or minimum value of the function.

And the period of each is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat.

The amplitude of each of the graphs of the sine and cosine functions is 1

The period of each of the graphs of the sine and cosine functions is 2π.

By definition, the amplitude of the graphs of the sine and cosine functions is defined as the vertical distance between the x - axis which is also called the sinusoidal axis and the peak value which is the maximum or minimum points located on the graph curve function. The basic graphs of sine and cosine function are the same and they have an amplitude equal to 1.

By definition, the period of the graphs of the sine and cosine functions is defined as the the distance between two peaks of the graph or the period for which the graph repeats. In this case the time period is always 2π.

For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?

Answers

Answer:

72 kg

Step-by-step explanation:

For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?

We are given the ratio

cement: sand:stones

= 1:2:4

The sum of proportion =

1 + 2 + 4 = 7

We are given the kg of sand = 144kg

Step 1

We find the total kg of cement, sand and stones = x

Using the proportion of sand,

2/7 of x = 144kg

2/7 × x = 144kg

2x/7 = 144kg

Cross Multiply

2x = 7 × 144kg

x = 7 × 144kg/2

x = 504kg

Therefore the total kg of cement, sand and stone = 504kg

Step 2

The amount of cement required is calculated as:

1/7 × 504 kg = 72 kg

Therefore, 72kg of cement is required.

A merchant bought 12 boxes of eggs containing 10 eggs each at the rate of rs 50 per box.He spent rs 40 on transportation.He sold the eggs at rs 12 per pair.Calculate his gain or loss%.

Answers

Given:

A  merchant bought 12 boxes of eggs containing 10 eggs each at the rate of Rs 50 per box.

He spent Rs 40 on transportation.

He sold the eggs at rs 12 per pair.

To find:

The gain or loss percentage.

Solution:

The cost of 1 box of eggs is Rs. 50. So, the cost of 12 boxes of eggs is:

[tex]12\times 50=600[/tex]

Number of eggs in 12 boxes is:

[tex]12\times 10=120[/tex]

He spent Rs 40 on transportation. So, total cost of 12 boxes of eggs is:

[tex]600+40=640[/tex]

Cost of each egg is:

[tex]\dfrac{640}{120}=\dfrac{16}{3}[/tex]

He sold the eggs at Rs 12 per pair. It means the selling price of two eggs is Rs 12. So, the selling price of each egg is:

[tex]\dfrac{12}{2}=6[/tex]

We need to find the gain or loss percentage.

Since [tex]\dfrac{16}{3}<6[/tex] it means the selling price is greater than the cost price, therefore it is gain.

The gain percent is:

[tex]Gain\%=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]

[tex]Gain\%=\dfrac{6-\dfrac{16}{3}}{\dfrac{16}{3}}\times 100[/tex]

[tex]Gain\%=\dfrac{\dfrac{18-16}{3}}{\dfrac{16}{3}}\times 100[/tex]

[tex]Gain\%=\dfrac{2}{16}\times 100[/tex]

[tex]Gain\%=12.5\%[/tex]

Therefore, the gain percent is 12.5%.

Applying the Pythagorean theorem, we have ΔPQR ≅ ΔABC. then we would have: ∠ACB = ∠PRQ = 90°

What is the Pythagroean Theorem?

The pythagorean theorem states that the square of the longest side (hypotenuse) of a right triangle is always equal to the sum of the squares of the other two sides (legs) of the right triangle.

Since we know that ΔPQR is a right triangle, then:

x² + y² = PQ²

We are also given that x² + y² = z², so by substitution, we have:

z² = PQ², which makes both triangles have corresponding congruent sides. Therefore, ΔPQR ≅ ΔABC.

Using the corresponding parts of the congruent triangles, we can conclude that: ∠ACB = ∠PRQ = 90°.
