Question

if tangents PA and PB from a point to a circle with centre 0 are inclined to each other at an angle of 20, then POA in equal to

(A) 70° (B) 55° (C) 100° (D) 40°​

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. (A) 50° (B) 60° (C) 70° (D) 80°. Since, the tangent at any point of a circle is perpendicular to the radius through the point of contact.
