Question

Find the measure of angle b
b/50

Answer 1

Answer:

X + 50 =180 ( being straight angle)

or, X =180 - 50

X = 130

Answer 2

Answer:

130°

Step-by-step explanation:

Angles in a straight line are supplementary to each other. Those angles are also called as Linear Pairs. Here , b & 50° are linear pairs.

So ,

b + 50° = 180°

=> b = 180° - 50°

=> b = 130°
