Question

In the adjoining figure , it is given that ZA=50 , ZB=70 and BO and CO are bisector of ZB and ZC respectively.Find the measure of ZBOC​

Answer 1

Answer:

∠BOC = 115

Step-by-step explanation:

We Know That:

∠A+∠B+∠C = 180

∠A = 50

∠B = 70

Therefore, ∠C = 60

In triangle ΔBOC,

∠OBC = ∠B/2 = 35

∠OCB = ∠C/2 = 30

∠BOC+∠OBC+∠OCB = 180

35+30+∠BOC = 180

65+∠BOC = 180

∠BOC = 115
