Question

Quizplus · Accepted Answer

The sum of the angles in a triangle is $180^{\circ}$. Since one angle is $42^{\circ}$ and the second angle is complementary to the first angle, the second angle must be $90^{\circ}$. Therefore, the third angle must be $180^{\circ} - 42^{\circ} - 90^{\circ} = 48^{\circ}$.
