So∠DHG = 7x-42, and since ∠FHC is directly opposite of it, it's the same value, 7x-42.
∠AGH should equal ∠CHF since they're both on parallel lines and line EF intersects them.
Therefore, ∠AGH =∠FHC:
3x-10=7x-42 (Subtract 7x and -10)
-4x=-32
x=8
∠DHG should be 8°
Answer:
34 should be added to it to make it 20

Answer:
x = -2.
Step-by-step explanation:
y + 2x = -1
y = -2x - 1
y =1/2x+4
Subtracting the last 2 equations:
0 = -2x - 1/2x - 1 - 4
5 = - 5/2 x
x = 5 / -5/2
= 5 * 2 / -5 = -2.
