Answer:

160

Step-by-step explanation:

5x-10+12x=16x

17x-16x=10

x= 10

exterior angle at C = 16x= 16×10 = 160°

Answer:

exterior ∠C = 160

Step-by-step explanation:

Exterior angle property: Exterior angle equals the sum of opposite interior angles.

∠A + ∠B = exterior ∠C

5x - 10 + 12x  = 16x  {Combine like terms}

 17x - 10 = 16x         {Add 10 to both sides}

        17x = 16x+ 10         {Subtract 16x form both sides}

17x - 16x = 10

         x = 10

exterior ∠C  = 16x = 16 * 10 = 160
