Question

How to find x and y, I very count used at this problem.

Answer 1

X=14, Y=75
(9x-1) and (5x-15) are supplementary angles.
So if you set up an equation, it looks like:

(9x-1)+(5x-15)=180. Simplify

14x-16=180

14x=196

X=14



(9x-1) and (y-20) are also supplementary angles. To solve for Y, we need to find (9x-1) first by plugging in x

(9(14)-1) =125

Now solve for Y

125+y-20=180

105+y=180

Y=75

Answer 2

X is parallel and y is the opposite
