Factor the polynomial below. 9x squared minus 16y squared

9x^2-16y^2=
(3x+4y)(3x-4y)

So first you would have to work with the y's since they are consecutive angles.Consecutive angles would add up to 180 so the problem would be
5(y+11)^0+4y-10=180 then simplify
10+4y-10=180
4y=180
y=45
Then plug in the y for the top problem and the add the answer to the x problem and set them to 180 because they are also a linear pair and you should get your answer
I got x=34
