-3x = -15 <em>divide both sides by (-3)</em>
-3x:(-3)=-15:(-3)
x = 5
It is c.
explanation:
20+130+h =180
when you solve you get h=50
130+g = 180
g= 50
50+60+f = 180
f=70

Answer:
x = 12
Step-by-step explanation:
Triangle DGH is isosceles with base angles at D and G. The external angle 134° at H is the sum of those two base angles, so we have ...
2(5x+7) = 134
5x +7 = 67 . . . . . divide by 2
5x = 60 . . . . . . . subtract 7
x = 12 . . . . . . . . divide by 5
