The measure of Angle A is 2x and Angle B is 60 when Angle A and Angles are supplementary angles. What is the value of x? A. 15 B
. 60 C. 120 D. 30
1 answer:
Answer:
B) 60
Step-by-step explanation:
<u>Given:</u>
- <A = 2x
- <B = 60
- <A and <B are supplementary angles (they add up to 180)
<u>Equation:</u>
<A + <B = 180
2x + 60 = 180
2x = 180 - 60
2x = 120
x = 60
