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°

Answer: 126°
Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get 
2x + 3x = 90°
5x = 90°
x = 18°
Plug in x for Angle 2, giving us Angle 2 = 54°
Angle 1 and angle 2 must add up to 180°
Subtract 54° from 180° and we get 126°
