There's a faster solution: Draw segment OC, recognize that segments OA, OB, and OC are all congruent because they are radii, create isosceles triangles AOB, COB, and AOC, state that the base angles of each triangle are congruent and sub in the base angles you already know, use the right angle theorem on the point of tangency to find
I too did with the difference that I applied triangle sum theorem in place of angle at the centre as twice the angle at the circumference theorem.Really enjoyed a nice video.thanks sir

I've got 21.5
I don't know whether it is correct
