Step-by-step explanation:
a + 50 + 30 = 180 (angle on a straight line = 180 degree)
a + 80 = 180
a= 100
d = 30 (alternate angles)
c= 50 (alternate angle)
b = a + d (exterior angle formed = sum of two interior opposite angles)
= 100 + 30
= 130
e = a + c (exterior angle formed = sum of two interior opposite angles)
= 100 + 50
= 150
PLEASE MARK AS BRAINLIEST :)
