Question

Finding a Missing Angle
Triangle A B C. Side A C has a length of 14 units. Angle A is question mark degrees, angle B is 68 degrees, and angle C is 82 degrees.

A student drew a triangle with a side length of 14 units and angle measures of 82° and 68°. The triangle is shown here with a missing angle.

AngleBAC must measure

Answer 1

Angle sum in a triangle is 180°.
A = 180° − (B + C) = 180° − (68° + 82°) = 180° − 150° = 30°.

So ∠BAC = 30°.
