a=180-79

a=101

c=83 (vertically opposite angles)

d=c (corresponding angles)

d=83

b=a(corresponding angles)

b=101

Hope it helps

a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.
