Answer:
m<B = 83°
Explanation:
The figure given is a parallelogram having opposite sides that area parallel to each other. Therefore, opposite angels are congruent while the adjacent angles are supplementary.
<A and <B are adjacent angles. Therefore,
m<A + m<B = 180°
97° + m<B = 180° (substitution)
m<B = 180° - 97
m<B = 83°
