Question

Help plsss !! Find each measure.

Answer 1

Answer:

x = 5, <DEG = 112, <GEF = 68, <DEF = 180

Step-by-step explanation:

<DEG + <GEF = 180

23x - 3 + 12x + 8 = 180

35x + 5 = 180

Subtract 5 from both sides

35x = 175

Divide each side by 35

x = 5

Plug x = 5 into <DEG

23x - 3

23(5) - 3

<DEG = 112

Plug x = 5 into <GEF

12x + 8

12(5) + 8

<GEF = 68

<DEF is a straight angle so it automatically is 180
