add 1 to both sides:
3x = 18
divide by 3:
x = 6
Answer:
ans: 31°
Step-by-step explanation:
<EFG = <EFH + <HFG
2x+52= 21 + ( x+31)
2x-x= 21 +31 -52
x= 0
so our question is to find <HFG so,
x+31°= 31°
Answer:
12 its right
Step-by-step explanation:
You need to find the slope of the line too. they use m to represent slope.

point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)
