Answer:

Your answer is c = 70°.

Step-by-step explanation:

First, you have to solve for the angle a and b in order to then solve for c.

b is vertical angles with 60° so thus making them congruent :

b = 60° .

For a, a is supplement angle with 130° meaning these two angles add up to 180° : a + 130° = 180° =>

a = 50°

Now solve for c, the triangle adds up to 180°.

a + b + c = 180°

50° + 60° + c = 180°

110° + c = 180°

c = 70°
