Question

Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102

Answer 1

∠C (Interior) =78°

∠B (Interior) = 62°

Explanation:

Given:

∠A (Interior) = 40°

∠C (exterior) = 102°

Computation:

∠C (Interior) = 180° - 102°

∠C (Interior) =78°

∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)

∠B (Interior) = 180° - 78° - 40°

∠B (Interior) = 180° - 118°

∠B (Interior) = 62°
