Answer:
Angle a is 101 degrees.
Angle b is 83 degrees.
Angle c is 83 degrees.
Angle D is 101 degrees.
Step-by-step explanation:
Angle c is 83 since the angle across is is also 83 and we call this a special type of angle.
Angle b is 83 degrees as well since it is across from c.
Angle a is 101 degrees for, 180 - 79 = 101 since it is a supplementary angle.
Angle d is also 101 degrees since it is across from a.
