Question

look at this diagram: if $overleftrightarrow{ik}$ and $overleftrightarrow{ln}$ are parallel lines and $mangle nmj = 43.8^{circ}$, what is $mangle kjh$?

Explanation:

Step1: Identify angle - relationship

$\angle NMJ$ and $\angle KJH$ are corresponding angles.

Step2: Apply property of corresponding angles

For parallel lines $\overleftrightarrow{IK}$ and $\overleftrightarrow{LN}$, corresponding angles are equal. So $m\angle KJH=m\angle NMJ$.

Answer:

$43.8$
