Answer:

6. x + x + 14 = 90

2x + 14 = 90

2x = 76

x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

x + x - 32 = 180

2x = 212

x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

7x - 80 = 3x

-80 = -4x

20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°
