Question

Explain your reasoning and include the equation you used to set up and solve this.

Answer 1

To find the interior angle of C, you must subtract 117 (the exterior) from 180 (a straight lines angle) to find the interior angle

Angle C = 63.

180 - 65 (angle a) - 63 (angle c) = 52 (angle b)

Angle B = 52
