Question

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​

Answer 1

Answer:

B) 60

Step-by-step explanation:

Given:

• <A = 2x
• <B = 60
• <A and <B are supplementary angles (they add up to 180)

Equation:

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60
