Answer:
x = 40
Step-by-step explanation:
The answer is x = 40. This is because the two angles that are x are 1. congruent and 2. supplementary with 100° (They all add up to 180°). I can show this with a simple equation.
1. 2x + 100 = 180
2. 2x = 80
3. x = 40

Answer:
x = 45
Step-by-step explanation:
Well here's what we know:
2x + 45 + x = 180
Solve from there:
3x = 135
x = 45
You can plug it back in to check:
2(45) + 45 + 45 = 180
90 + 80 = 180, so it checks out :)
