Answer:

x = 8

Step-by-step explanation:

There are two ways of answering this:

1.)Supplementary Angles/Linear pair:

(5x- 15) + (20x - 5) = 180°

25x - 20 = 180

25x - 20 +20 = 180 + 20

25x = 200

x = 8

2.) Vertical angles theorem:

(5x - 15) = (3x + 1)

5x - 3x -15 + 15 = 3x - 3x + 1 +15

2x = 16

x = 8
