Question

Solve for X in the picture below. Thanks

Answer 1

x = 50

Explanation:

3 (50) + 10 = 160

(50) - 30 = 20

160 + 20 = 180

Since they add up to 180 you know its correct :)

Answer 2

x = 50

Explanation:

The two angles shown with measures are a linear pair. They are supplementary angles, so their measure have a sum of 180°.

x - 30 + 3x + 10 = 180

4x - 20 = 180

4x = 200

x = 50
