Question

The sum of ∠m and ∠ n is 188°. Find the measure of ∠ b.

Answer 1

Answer:

angle m = angle n (Vertically opposite angle)

Sum of angle m and angle n is = 188°

So,

angle m + angle n = 188°

=> angle m + angle m = 188°

=> 2 angle m = 188°

=> angle m = 188°/2

=> angle m = 94°

angle m = angle n = 94°

angle b = 180° - 94°

= 86°

Ans. 86°
