Answer: h = -17.5
Step-by-step explanation:
Move the like-terms together on the right side and the other to the left side.
1.6h - 4h = 72 - 30
Subtract both sides:
1.6h - 4h = -2.4h
72 - 30 = 42
-2.4h = 42
Divide -2.4 by both sides
-2.4h/-2.4 = 42/-2.4
h = -17.5
And
consecutive angles have sum 180°
- 7y+3+86=180
- 7y+89=180
- 7y=91
- y=13
So
- 5z+4+86=180
- 5z=180-90
- 5z=90
- z=14
