Expert Answer
let P be the point from where tangents are drawn.
Let A and B be the points of contact and O be the center.
consider quad PAOB.
angle PAO=90
and
angle PBO=90... angle made by the radius thru' the point of contact with the tangent is 90 degrees.
here the sum of two angles of the quad is 180, so the sum of the other two angles also must be 180.
so anglesAPB and AOB are supplementary.
