Two intersecting lines create four angles with the same vertex, labeled A , B , C , and D . Angle B is adjacent to ∠A and ∠C . Find m∠A if m∠C=75° .(1 point) explain your answer why
If angle C is 75 degrees, and angle B is adjacent to angle C, then angle B is also 75 degrees. Since angle B and angle A are adjacent, they also share the same measure, which means m∠A would also be 75 degrees.
