Answer:

x = 60°

2x = 120°

Explanation:

A straight line = 180°

we are given supplementary angles (sum up to 180°)

so 2x + x = 180°

3x = 180° combine like terms, x

3x / 3 = 180° / 3 divided both sides by 3 to get x alone

x = 60°

and the 2x angle is 2(60°) = 120° by plugging x in

Let me know if you have any questions, Happy to help !
