Question

Can someone help please l

Answer 1

Explanation:

Since DE=FE, we know GE is angle bisectors of angle G.

Thus, set those two expressions equal to each other.

3x+8= 5x-12

20=2x

x=10

Answer 2

x = 10

Explanation:

DE = EF, GE = GE, m∠D = m∠F = 90°

so

ΔDGE = ΔFGE

then

3x + 8 = 5x - 12

3x - 5x = -12 - 8

-2x = -20

2x = 20

x = 10
