Question

angle jkl is a right angle. the measure of angle mkl is 25°. the measure of angle jkm is x°. what is the value of x?

Explanation:

Step1: Recall angle - addition property

Since $\angle{JKL}=\angle{JKM}+\angle{MKL}$ and $\angle{JKL} = 90^{\circ}$ (right - angle), $\angle{JKM}=x^{\circ}$ and $\angle{MKL}=25^{\circ}$.
So, $x + 25=90$.

Step2: Solve for x

Subtract 25 from both sides of the equation $x + 25=90$. We get $x=90 - 25$.
$x = 65$.

Answer:

$65$
