Question

angle jkl is a right angle. the measure of angle mkl is 50°. the measure of angle jkm is x°. what is the value of x?

Explanation:

Step1: Recall angle - addition property

We know that $\angle{JKL}=\angle{JKM}+\angle{MKL}$.

Step2: Substitute known values

Since $\angle{JKL} = 90^{\circ}$ (right - angle), $\angle{MKL}=50^{\circ}$, and $\angle{JKM}=x^{\circ}$, we have the equation $90=x + 50$.

Step3: Solve for x

Subtract 50 from both sides of the equation: $x=90 - 50$.

Answer:

$40$
