Answer:
The answer is A. 50
Step-by-step explanation:
because the angle made by tangents are bisected and hence becomes 40,40(oap=obp) (by theorem:If two tangents are drawn to a circle from an external point ; then (i) they subtend equal angles at the centre. (ii) they are equally inclined to the line segments ; joining the centre to that point.)
Also, angle at point of contact ,oap is 90
Hence by angle sum property, angle poa is 50
