Answer 1

Step-by-step explanation:

c = 75 , 5a = 2c

c = a+b

5a = 2c

a = 2c/5

a = 2×75/5

a = 2×15

a = 30

a+b = c (( alternate interior angle ))

30+b = 75

b = 45.

b+d = 180

45+d = 180

d = 135

Answer 2

Answer:

5a = 2c

=> a = 2/5 c = (2/5)×75 = 30°

now a+b = c ( alt. int. angle)

=> b = 45°

now b+d = 180°

=> d = 135°
