All you needed to do was plug in 5 into C
Put together they will make a 90 degree angle so 15x+8x -2= 90 combine like terms you get 23x-2=90 +2= 92= 23x now 92/23 is 4 so x= 4
EG bisects angle DEF, so the two angles DEG and GEF are congruent. This means
3x + 8 = 5x - 4
Solve for x :
8 + 4 = 5x - 3x
2x = 12
x = 6
Then the measure of angle GEF is
5x - 4 = 5*6 - 4 = 26
degrees.
Answer:
70
Step-by-step explanation:
complementary angles are 2 angles that add up to 90, the first angle is already 20 so just subtract 90-20 to find other angle
