Supplementary angles sum up to 180 degrees.
2x - 4 + 2x + 4 = 180
4x = 180
x = 45
Therefore,
m<9 = 2(45) - 4 = 90 - 4 = 86 degrees
m<10 = 2x + 4 = 90 + 4 = 94 degrees.
Answer:
16
Step-by-step explanation:
I think you're referring to the nearest whole number, which should be 16 because that's after the decimal point
Distribute the 2
2x-8=8
Add 8 to both sides
2x=16
divide by two
x=8
