Question

find the value of y in following figures​

Answer 1

Answer:

First we need to find angle ABC,

So,

According to Linear Pair ,

Angle ABC = 180° - 120°

= 60°

Therefore , According to Angle Sum Property of Triangles,

70°+60°+y = 180°

=> 130° +y = 180°

=> y = 180°-130°

=> y = 50°

Therefore , 50° is your answer
