Can someone help me please, TEST - Need help Need help to solve these 2 problems. I need to show the work

THANK YOU

14. d

15. b

Step-by-step explanation:

steps for #14:

1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.

  (x + 5) + (x - 9) = 90

2. combine like terms.

  2x - 4 = 90

3. solve for x.

  2x = 94

     x = 47

4. plug x into both formulas to find the measurements of each angle.

  47 + 5    AND     47 - 9  

     d. angle DFG = 52, angle JKL = 38

steps for #15:

1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.

  (x - 39) + (x + 61) = 180

2. combine like terms.

  2x + 22 = 180

3. solve for x.

  2x = 158

     x = 79

4. plug x into both formulas to find the measurements of each angle.

  79 - 39    AND      79 + 61

     b. angle 1 = 40, angle 2 = 140

8 2/3 is the answer

step-by-step explanation: just use a calculator
