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
