Question

How would I solve this?

Answer 1

I hope this is clear and helps

Answer 2

Make (2x - 20) = 130 because they are vertical angles.

2x - 20 = 130

Add 20 to both sides.

2x = 150

Divide both sides by 2.

x = 75

Now make (4y + 10) + 130 = 180 because they are supplementary angles.

(4y + 10) + 130 = 180

Combine like terms.

4y + 140 = 180

Subtract 140 from both sides.

4y = 40

Divide both sides by 4.

y = 10
