Question

What is the value of y?

Answer 1

Answer: B. 65°

Reason: The linear pair formed by 130° and the angle adjacent to it is 180°.

Therefore, the adjacent angle is 50° (180°-130°)

Now since the other two angles are equal to y°,

Therefore, 50°+y°+y°=180°(Angle sum property of triangles)

50°+2y°=180°

2y=130°

y=65°
