2)  m∠CBD = 60         3) x=15; 95 and 85     4) 12 = x; 98 for both angles

Step-by-step explanation:

2)  2x + 14 + x + 7 = 90       The angles add up to 90 degrees

    3x + 21 = 90                   Combine like terms

          - 21  - 21                    Subtract 21 from both sides

    3x = 69                           Divide both sides by 3

     x = 23

Plug 23 in the equation

2(23) + 14

46 + 14

60

3)  2x + 65 + 3x + 40 = 180       The angles add up to 180 degrees

    5x + 105 = 180                      Combine like terms

          - 105  - 105                      Subtract 105 from both sides

5x = 75                                       Divide both sides by 5

x = 15

Plug in 15 into both equations

2(15) + 65 = 95

3(15) + 40 = 85

4) 5x + 38 = 9x - 10

  - 5x         - 5x                 Subtract 5x from both sides

38 = 4x - 10

+ 10       + 10                      Add 10 to both sides

48 = 4x                              Divide both sides by 4

12 = x

Plug in 12 into both equations

5(12) + 38 = 98

9(12) - 10 = 98
