Question

in the given figure the length of arcs a b and b c are in the ratio 3 is to 2 if angle aob is 96 degree find angle BOC and angle abc

Answer 1

Answer:

Step-by-step explanation:

OAB and OBC are isosceles triangle

Let angle oab=abo=x

Let angle obc=bco=y

2x+96=180

x=42

ab/bc=3/2

2ab=3bc

2x96*2πr/360=3xα*2πr/360

(where α=angle boc)

2*96=α*3

α=64

in triangle boc,

2y+64=180

y=58

x+y=42+58=110

And hence,

angle boc=64

angle abc=110
