Rahul Bamel · Answer

given AOC =20 ,ABO =50
SO AOC+BOC+ABO=180(LINEAR PAIR AXIOM)
20+BOC+50=180
BOC=180-70
BOC=110

If o is the centre of the circle angle ABO=50 degree and angle ACO=20 degree find the measure of angle BOC. I n f i g u r e , i f O i s t h e c e n t r e o f t h e c i r c l e , ∠ A B O = 50 ° a n d ∠ A C O = 20 ° , f i n d t h e m e a s u r e o f ∠ B O C .
