Answer:

Your answer Exterior C is 160°

Interior C is 20°

Explanation:

<A + <B + <C = 180°

<Left C + <Right C = 180°

<A + <B = <Right C

(5x - 10)° + 12x° = 16x

17x - 10 = 16x

x = 10

<A = 5x - 10

<A = 5*10 - 10

<A = 50 - 10 = 40°


<B = 12x

<B = 12*10

<B = 120°

<A + <B = <Right C.

40° + 120° = 160°
