Question

What does number does x represent?

Solve for x.

Answer 1

x=10

Explanation:

Answer 2

x=25

Explanation:

Since the line is straight, its degrees sum up to 180°. Because of this, you can subtract 60 from 180 to get 120°. Now you know that the missing angle measures 120°. Since you know this, you can set 4x+20 equal to 120. Subtract 20 from both sides to get 4x=100, then divide 100 by 4 to get 25. x=25.
