Answer:
120⁰=2y+y (Exterior angle property)
120⁰=3y
40⁰=y
y = 40⁰
2y = 2×40⁰ = 80⁰
120⁰+x=180⁰(Linear pair)
x=180⁰-120⁰
x=60⁰
x = 60⁰
Mark as brainliest please....

we can also make this by another process.
but this is possible only when if another two angles are not given. but here two angles are given so, we have to solve this by first one method.
