The two tangents from an external points P to a circle with centre at O are PA and PB. If `angle APB=70^(@)` then the value of `angle AOB` is

In the figure, PA is a tangent from an external point P to the circle with centre O and diameter AB. If angle POB = 110^@ , then the measure of angle APO is:

Two tangents PA and PB are drawn from an external point P to a circle with centre at O. If AOB = 105^(@) the A hat(P) B is :

In the figure, PA is a tangent from an external point P to a circle with centre O. If anglePOB = 115^(@) , find angleAPO .

If PA and PB are tangents drawn from an external point P to a circle with centre O such that angle APB = 70^@ , then angle OAB is equal to: यदि PA और PB एक बाहरी बिंदु P से केंद्र O के साथ एक वृत्त में खींची गई स्पर्श रेखाएँ हैं जैसे कि angle APB = 70^@ तो angle OAB बराबर है:

PA and PB are two tangents drawn from an external point P to a circle with centre C and radius=4cm If PA_|_PB then length of each tangent is

From an external point P, tangent PA=PB are drawn to a circle with centre O. If anglePAB=50^@, then find angleAOB .

In the adjacent figure APB is a tangent to the circle with centre 'O' at a point P. If angle QPB = 50^@ then the measure of angle POQ
