Answer:

B = 90

C = 44

D = 46

Step-by-step explanation:

a right angle means that it is 90 degrees, and the combination of all angles must be 180 degrees. This means that angles D and C must equal 90. If you add together the equations assuming the answer is 90, you can solve for x.

(5x - 29) + (2x + 14) = 90

7x - 29 + 14 = 90

7x - 15 = 90

7x = 105

(7x = 105) ÷ 7

x = 15

When you get the value for x you can then plug it into the individual equations to find the degree of the angle

5(15) - 29

75 - 29 = 46

Angle D = 46

2(15) + 14

30 + 14 = 44

Angle C = 44

To check your answer you can add all of the angles together and if they equal 180 then your answer is correct

44 + 46 +  90

90 + 90 = 180
