130 and 2c are vertical angles which means they are congruent. So set them equal to each other and solve for c.

130 = 2c
130/2 = c
65 = c

Hope this helps :)

By the vertical angles theorem which states that two vertical angles are equivalent, we construct the equation 2C = 130

Solve for C.

We can divide both sides by 2 to get the answer.

2C = 130
2C / 2 = 130 / 2

C = 65

So, C is equal to 65 degrees.
