Answer:

$m\angle JKM = 162^\circ$

Explanation:

Angle Bisector

An angle bisector is a ray that divides an angle into two congruent angles, each having a measure exactly half of the original angle.

We are given ray KR bisects angle JKM.

This means angle JKM is divided into two congruent angles JKR and RKM. We know:

$m\angle JKR = 81^\circ$

Thus, the measure of angle JKM is twice the measure of JKR. Therefore:

$m\angle JKM = 2*81^\circ= 162^\circ$

$\mathbf{m\angle JKM = 162^\circ}$
