Answer 2

Step-by-step explanation:

a) 90+ 2x + (2x + 20) = 180

2x + 2x = 180- (90 + 20)

4x = 180- 110

4x = 70

x = 70/4

x = 17.5

b) 95= x + (x + 5) (in triangle, an exterior angle= sum of 2 opposite interior angles )

95 = 2x +5

95- 5 = 2x

90 = 2x

90/2 = x

45 = x

c) 4x - 4 = (3x + 5) + (2x - 39)

4x - 4 = 3x + 5 + 2x - 39

4x - 4 = 5x - 34

-4 + 34 = 5x - 4x

30 = x
