Answer:
b is the answer I just took the test
Step-by-step explanation:
d.
angle DHE = angle GHF
Let's call it X
Then DHG = EHF = 180-X
(supplementary angles)
angle HFG = angle HDE
(alternate angles)
x=9/2
10
-1 =s
7 = -10s - 3
Add 3 to each side
7+3 = -10s - 3+3
10 = -10s
Divide by -10
10/-10 = -10s/-10
