If tangents PA and PB from a point P to a circle with centre O are inclined to each other at an angle of 70^(@) , then /_POA is equal to

If tangents PA and PB from a point P to a circle with centre O are inclined to each other at an angle of 80o then /_POA is equal to 50o (b) 60o(c)70o (d) 80o

Two tangents TA and TB to circle with centre O are inclined to each other angle of 70^(@) . Then, Find angleOAB .

In Figure 4,PQ and PR are tangents drawn to a circle with centre O from an external point P . If /_PRQ=70^(@), then find /_QPR and /_OQR

In figure, if PQR is the tangent to a circle at Q whose centre is O, AB is a chord parallel to PR and angleBQR=70^(@) then angleAQB is equal to

In figure, if PQR is the tangent to a circle at Q whose centre is O, AB is a chord parallel to PR and angleBQR=70^(@) then angleAQB is equal to

The length of tangent from an external point P on a circle with centre 0 is always less than OP.

The length of tangent from an external point P on a circle with centre 0 is always less than OP.

PA and PB are two tangents to a circle with centre 0. from a point P outside the circle. A and B are points on the circle. If angleAPB= 70^@ then angleOAB is equal to:

From the point P(-1,-2) ,PQ and PR are the tangents drawn to the circle x^(2)+y^(2)-6x-8y=0 .Then angle subtended by QR at the centre of the circle is
