Step-by-step explanation:

m < D = 180- ( 98 + 36 )= 46

m < D = m < B = 46

The measure of angle B is : 46°

What is a parallelogram?

A parallelogram is a quadrilateral with four sides and four angles.

The opposite sides of this parallelogram are parallel and the opposite angles are equal.

Analysis:

From the definition above, a parallelogram has opposite angles equal, which means ∠D = ∠B

Consider ΔACD

∠A + ∠C + ∠D = 180( angles in a triangle)

∠D + 98 + 36 = 180

∠D + 134 = 180

∠D = 180 - 134 = 46°

Therefore ∠B = 46°

In conclusion, ∠B is 46° because it is an opposite angle to D and opposite angles of a parallelogram are equal.
