Hi,I need your help with bisecting angles im stuck. Suppose JK bisects angle LJM. The measure of angle LJK = (-10x + 3) and the measure of KJM = (-x + 21)º. Which equation represents the best way to find the measure of angle LJM? (Hint: Sketch the situation first.)

as the angle LJM is bisected by JK

the -10x + 3 = -x + 21

or -9x = 18

x = -2

substitute angle LJK = (-10 x -2) + 3
                                 = 23

                Angle KJM = -(-2) + 21
                                   = 23

proving KJ bisects

then LJM = 23 + 23 = 46
