Two angles of a triangle are $30^{\circ}$ and $110^{\circ}$. What is the measure of the third angle?
A) $220^{\circ}$
B) $40^{\circ}$
C) $140^{\circ}$
D) $-50^{\circ}$

Question

Quizplus · Accepted Answer

The sum of angles in a triangle is $180^{\circ}$. Subtracting the given angles from $180^{\circ}$ gives the third angle: $180^{\circ} - 30^{\circ} - 110^{\circ} = 40^{\circ}$.
