Answer:
20°
Step-by-step explanation:
4x+27°+9x-115°=107°
4x+9x + 27°-115°=107°
13x-88°=107°
add 88 on both sides
13x=195°
divide 13 on both sides
x=15
9(15°)-115°
135°-115° = 20
The answer is 20
25 degrees

3 6/8
5 = 5
10/8 = 1 2/8
5 - 1 = 4
4 - 2/8 = 3 6/8
-2(-1) + 7y = -54
2 + 7y = -54
-2 -2
7y = -56
Divide by 7
y = -8
