Two angles of a triangle measure 50° and 60°. What is the third angle?

Correct answer: D. 70°

The angles of every triangle add up to 180°, so the third angle is 180° − 50° − 60° = 70°. This rule holds for every triangle, whatever its shape or size. Since the third angle is less than 90°, this triangle is acute.
