4. what is the measure of angle khj?

Question

Accepted Answer

# Explanation:
## Step1: Use the exterior angle theorem
The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. In triangle $HIJ$, $\angle KHJ$ is an exterior angle. The two non - adjacent interior angles are $\angle J = 85^{\circ}$ and $\angle I=47^{\circ}$.
## Step2: Calculate $\angle KHJ$
$$
\begin{align*}
\angle KHJ&=\angle J+\angle I\
&=85^{\circ}+ 47^{\circ}\
&=132^{\circ}
\end{align*}
$$

# Answer:
$132^{\circ}$
