Answer 2

Answer

x=20

y=50

How I Did This

Any time there are two angles next to each other in a straight line, they are supplementary, meaning they add up to 180.

Also, all triangles' angles add up to 180.

With this information, we can solve for x and y.

First we find the unknown side in the first triangle

180=91-?

-91   -91

89=?

Now we can solve for x.

Combine like terms

71+89+x=180

Subtract 160 from both sides

160+x=180

-160     -160

x=20

Now, we can solve for y.

91+31+x=180

Combine like terms.

130+x=180

Subtract 130 from both sides.

130+x=180

-130     -130

x=50
