Answer:
Angle A is 101
Angle B is 79
Angle C is 83
Angle D is 97
Explanation:
Vertical angles are congruent, which applies to C.
Lines are parallel so 79 and angle B are the same
Angle a is 101 because its a supplementary angle
Angle D is 97 because its also a supplementary angle so you subtract 83 from 180.
