To find the interior of Y

Y = 180 - 135

Y = 45

The interior of Z is 49 because the angles are mirrored to each other

then, to find x,

X = 180 - 45 - 49

X = 86

so your answer should be 86.

Given:

$m\angle WXZ=109^\circ$

m∠2 is 19° more than m∠1.

To find:

The value of m∠1.

Solution:

Let the measure of ∠1 be x.

Then, $m\angle 2=x+19^\circ$

$m\angle WXZ=109^\circ$ , it means the sum of m∠1 and m∠2 is 109°.

$m\angle 1+m\angle 2=109^\circ$

$x+(x+19^\circ)=109^\circ$

$2x+19^\circ=109^\circ$

$2x=109^\circ-19^\circ$

$2x=90^\circ$

Divide both sides by 2.

$x=\dfrac{90^\circ}{2}$

$x=45^\circ$

Therefore, the value of m∠1 is 45°.

Question 5 (1 point)

ElenaW [278]

Answer:

The volume of the shape is 560 ft^3

Step-by-step explanation:

To find the volume of the figure, we need to multiply the base area by the height of the figure

mathematically, we have the base area as a rectangular shape and its area is the product of its side lengths

We have this as 8 ft * 10 ft = 80 ft^2

So multiplying this by the height which is 7 ft, we have this as;

7 ft * 80 ft^2 = 560 ft^3

An art teacher has 9 students in a pottery class. He has 21.06 pounds of clay he divides evenly among all the students. Each stu

0.78 because 21.06 divided by 9 is 2.34 and divide by three because you have to make three sculptures so you get 0.78 :)

Triangle XYZ, XY= 80, ZY= 64 XZ= 48 what is the cosine

SVETLANKA909090 [29]

Answer:

$cos=\frac{4}{5}$

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.

I attached a picture of what I think the triangle would look like.

If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).

Looking at my picture then:

$cos=\frac{64}{80} \\cos=\frac{8}{10} \\cos=\frac{4}{5}$ .
