Question

in the adjoining figure bo and co is are the bisector of of angle b and angle c respectively. if angle a = 50 degree then find angle BOC​

Answer 1

Answer:

A+b+c = 180

50+b+c= 180

b+c = 130 ...(1)

divide equation (1) by 2

1/2(b+c) = 65....(2)

now in triangle obc

o+1/2(b+c) = 180

o+65= 180 ( from (2))

o= 180-65= 115
