Question

if tangents PA and PB from a point P to a circle with centere O are inclined to each other at angle 80 degree, then angle POA is equal to
1.50 degree
2. 60 degree
3.70 degree
4.80 degree
choose option and explain it ​

Answer 1

Answer:

If tangents PA and PB from a point P to a circle with centre O are inclined to each other at angle of 80°, then ∠ POA is equal to. ... Since, the tangent at any point of a circle is perpendicular to the radius through the point of contact
