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}
