I need help on this homework question
KL and KJ are opposites rays.Angle 1 is congruent to angle 2 and KM bisects angle NKL.If angle JKN=9x+5 and angle MKL=2x+3,what is angle MKN?
Please help me....

Don't know what angles 1 and 2 are, but
angles JKN + NKM + MKL = 180
MKN = NKM, since KM bisects angle NKL

9x+5 + 2x+3 + 2x+3 = 180
13x + 11 = 180
13x = 169
x = 13

MKN = 2x+3 = 29
