Question

In a parallelogram ABCD, if angle A = 70°, then the measure of angle B is​

Answer 1

Answer:

B=110°

This is my answer

Answer 2

$\large\bold{\underline{\sf{\blue{Given:-}}}}$

In a parallelogram ABCD , angle A = 70°

$\large\bold{\underline{\sf{\blue{To\:find:-}}}}$

The measure of angle B = ?

$\large\bold{\underline{\sf{\blue{Solution:-}}}}$

We know that,

In a parallelogram , adjacent angles are supplementary,

Hence,

Angle A + angle B = 180°

Angle B = 180° – Angle A

Angle B = 180° – 70°

Angle B = 110°

Hence, Angle B = 110°
