Question

find the value of x step by step​

Answer 1

now ..

ang (BAO)=angABO)=30° [as,OB and OA both the radius of the same circle,,so ∆ABO is an Isosceles triangle]

ang(OAC)=ang(OCA)=50° [as,OC and OA both the radius of the same circle,,so ∆ACO is an Isosceles triangle]

therefore...ang(BAC)=30°+50°=80°

therefore...

ang(BOC)=2*ang(BAC)=2*80°=160°

therefore...X=160°

Hope this helps you.....
