Answer:
The measurement of the required angle = 116°
Step-by-step explanation:
Let the measure of its supplement = x
The measurement of the required angle = 2x - 12
x + 2x -12 = 180
3x - 12 = 180
3x = 180 + 12
3x = 192
x = 192/3
x = 64°
The measurement of the required angle = 2 * 64 - 12 = 128 - 12 = 116°
The answer is c. See explanation below.
Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20 Distribution
10x=0 add 20 to both sides
x=0 divide by 10 on both sides
