Question

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)Responses75°75 degrees105°  105 degrees180°  180 degrees15°

Answer 1

If angle C is 75° and angle B is adjacent to angle C, then angle B is also 75°.

Since angle A and angle D are vertical angles, they are congruent. Therefore, angle A is also 75°.

So, m∠A = 75°.
