Answer:

a = 68°, b = 112°, c = 68°

Explanation:

112° is a vertical angle to the one with the line through it, therefore they are equal. The angle opposite to b is equal to the one opposite to 112°. b and 112° are vertical angles, so b = 112°. a is a supplementary angle to b, so b + a = 180°. 112° + a = 180°, so a = 68°. c is vertical to a, c = 68° as well.

I hope this helps!
