Question

1. identify the angles as complementary or supplementary. then find the missing angle. (mangle qav = 90^{circ})

Explanation:

Step1: Identify angle - type

Since $\angle QAV = 90^{\circ}$, the two angles are complementary. Complementary angles add up to $90^{\circ}$.

Step2: Calculate the missing - angle

Let the missing angle be $x$. We know that $x+67^{\circ}=90^{\circ}$. So, $x = 90^{\circ}-67^{\circ}$.
$x = 23^{\circ}$

Answer:

The angles are complementary and the missing angle is $23^{\circ}$
