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) Responses 75° 75 degrees 15° 15 degrees 180° 180 degrees 105°
1 answer
If the lines intersect, then angle A and angle C are vertical angles and are congruent. So, if m∠C is 75°, then m∠A is also 75°. Answer: 75°.
