Step-by-step explanation:

False. Obtuse is always greater than 90°.

Answer:

False

Obtuse triangles can't have right angles

Answer:

I got that it was 68.2mm.

Step-by-step explanation:

Option A is correct, the length of the hypotenuse of the triangle is  68.2 mm.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. That is:

cos(θ) = adjacent/hypotenuse

We know that cos(θ) = 0.755 and the length of the adjacent side is 51.5 mm.

Let's denote the length of the hypotenuse by "h".

Then we can solve for "h" as follows:

cos(θ) = adjacent/hypotenuse

0.755 = 51.5/h

h = 51.5/0.755

h = 68.21 mm

Therefore, the length of the hypotenuse of the triangle is approximately 68.2 mm.

Answer:

≈ 20.8 ft

Step-by-step explanation:

A right triangle is formed between the wall, the ground and the ladder.

The ladder is the hypotenuse , the wall and ground are the legs.

let h be the height of the wall, then using Pythagoras' identity

h² + 33² = 39²

h² + 1089 = 1521 ( subtract 1089 from both sides )

h² = 432 ( take the square root of both sides )

h = [tex]\sqrt{432}[/tex] ≈ 20.8 ft ( to the nearest tenth )

Question:

Discus the advantages and disadvantages of histograms versus stem-and-leaf plots

Answer:

C. Stem-and-leaf plots are easier to make and and can contain more information than histograms. However, they are not very useful for large data sets

Step-by-step explanation:

A stem and leaf plot is a graphical presentation of quantitative data similar to an histogram. However, a stem and leaf plot retains and present the values of the original in the data set such that individual data values can be seen and can then be used to make analysis

The stem and leaf plot consists of a stem and a leaf  arranged in the order of place value, such that the numbers having a common highest place value are arranged on a row in a stem and leaf plot and therefore a stem and leaf plot is easier to make or construct than an histogram

However, it is very rare to find stem and leaf plots having more than 50 datasets or observations.

Answer:

y = 0, y = [tex]\frac{1}{3}[/tex], y = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Given

12y³ - 13y² + 3y = 0 ← factor out y from each term

y(12y² - 13y + 3) = 0

y(3y - 1)(4y - 3) = 0 ← in factored form

Equate each factor to zero and solve for y

y = 0

3y - 1 = 0 ⇒ 3y = 1 ⇒ y = [tex]\frac{1}{3}[/tex]

4y - 3 = 0 ⇒ 4y = 3 ⇒ y = [tex]\frac{3}{4}[/tex]

Answer:

x < 11

Step-by-step explanation:

-9x + 40 > -59

Subtract 40 from each side.

-9x > -99

Divide by -9 on each side. (flip the symbol)

x < 11

or, x=180

or,34=180

or,180-34

or x=146

Now,

or, y=146

or,18=146

or146-18

or, y=128

there is x is 34 and its all side angle is 180 degree So put x =180 and then put x value is 34 =180 and there is no values in front of 34 so there will be + and if +so in another side it will be - and then after put 180-34=146
