Question

Find the value of each variable.

Answer 1

2x=76 since oposite angles are equal
2x=76
divide 2
x=38

on line, angles add to 180
2x+y=180
76+y=180
minus 76 both sides
y=104

y=104
x=38

3rd option

Answer 2

2nd option bc x and y are supplementary, therefore they equal 180. 52 x 2 = 104. 104 +76 = 180. and it can also be the third option because they equal 180.
