A70°

B110°

C55°

D90°

Answer:

A. 70°

Read Explanation:

Since ABCD is a parallelogram:

Properties of Parallelogram

  • Opposite angles are equal.

  • Adjacent angles are supplementary (add up to 180°).

Given ∠A = 110°.

Finding ∠B

Since ∠A and ∠B are adjacent angles, they are supplementary:

∠A + ∠B = 180°

110° + ∠B = 180°

∠B = 180° - 110°

∠B = 70°

So, the measure of ∠B is 70°.
