The triangle angle-sum theorem says that all those angles added together equal 180. Therefore, 120+x+x+16=180 and 2x+136=180 and 2x=44. Therefore, x = 22, which is angle B.
Answer:
D. 20°, 60°, and 100°
Step-by-step explanation:
basically you're testing which set adds up to 180°:
D should immediately catch the eye since it has a simple 100°, and 60+20 is 80, making D the correct answer
a: 189°
b: 90°
c: 120°
d: 180°

Answer:
x=43
Step-by-step explanation:
Since the lines are parrallel, the angle underneath the one you are finding is equal to 65. To find the total value of (x+72) you subtract 65 from 180, giving you 115.
x+72 = 115
then you subtract 72 from both sides
x=43
