Answer:

135 degrees

Step-by-step explanation:

Angle DEG and GEF are supplementary (their measures add up to 180 degrees).

(18x - 9) + (4x + 13) = 180

22x + 4 = 180

22x = 176

x = 8

The measure of angle DEG is 18(8) - 9 = 144 - 9 = 135 degrees

Answer:

Step-by-step explanation:

Assuming DEF is a straight line, the two angles are supplementary.

(18x - 9) + (4x + 13) = 180

                22x + 4 = 180

                       22x = 176

                           x = 8

m∠DEG = (18(8) - 9) = 135°
