please help me to do this question ​

Answer 1

join oc

ap=ac( a is an external point)

^aop=^aoc take this as equation no 1

bc=bq(tgt drawn from external point)

^boq=^boc take this as equation no 2

here poq is diameter

therfore, ^poa+^aoc+^boc+^boq=180°

^aoc+^aoc+^boc+^boc=180°

2^aoc+2^boc

take 2 as common

2[^aoc+^boc) = 180° ( 2 one sa,2 9 sa 18)

^aoc+^boc=90°

^aob=90°

^ mtlb angle hota hai
