Answer:

66 = ∠JKN

Step-by-step explanation:

∠JKM = 99

∠LKM = 66

KN bisects means middle point divides into two equal parts

so first lets find ∠LKN and ∠NKM

66/2 = ∠LKN and ∠NKM each

33 = ∠LKN

33 = ∠NKM

so if we add ∠JKL + ∠LKN + ∠NKM = 99

∠JKL + ∠LKN + ∠NKM = 99

∠JKL + 33 + 33 = 99

∠JKL  + 66  = 99

∠JKL = 99-66

∠JKL = 33

now to find ∠JKN we must add

∠JKL + ∠LKN = ∠JKN

33 + 33 = ∠JKN

66 = ∠JKN
