Answer:
x = 6
∠B = 126
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x + 78°
∠B = 2x + 114°
8x + 78° = 2x + 114°
8x - 2x = 114 - 78
6x = 36
x = 36/6
x = 6
plugin x into ∠B = 2x + 114°
∠B = 2x + 114°
∠B = 2(6) + 114°
∠B = 126
Answer:
I believe it is c
Step-by-step explanation:
Answer:
2(x-9)
Step-by-step explanation:
X=-a/6
Because you need to isolate x
B. Step 2 should’ve brought the negative sign down with the 72.
You can see that the equation went from -72 = 4x -30 to
72 = 4x - 30
