angle BOC= 90+1/2*A
100=90+1/2*A
100-90=1/2*A
10=1/2*A
A=2*10
A=20
100=90+1/2*A
100-90=1/2*A
10=1/2*A
A=2*10
A=20
plz mark brainliest
but how can you say that angle BOC is equal to 90+1÷2 of angle A
just check out Rd sharma grade 9 this formula has been proved
if you use this in your exams first you will have to prove this if it is for 3 or 2 marks
