Answer:
Step-by-step explanation:
9x + 20 +7x = 180 {Linear pair}
9x + 7x + 20 = 180 {Combine like terms}
16x + 20 = 180 {Subtract 20 form both sides}
16x = 180 - 20
16x = 160 {Divide both sides by 16}
x = 160/16
x = 10
7x = 7*10 = 70
2y = 7x {Vertically opposite angles are equal}
2y = 70 {Divide both sides by 2}
y = 70/2
y = 35
