this is an AP

a=4-1/n ,d=-1/n

so Sn=n/2{ 2(4-1/n) +(n-1)(-1/n)}

=n/2 x (8-2/n-1+1/n)

=n/2 x(7-1/n)

=n/2 x (7n-1)/n=(7n-1)/2

Lionel Messi⚽️ 6 years, 10 months ago

Let ABCD be the quadrilateral circumscribing a circle with centre O. The quadrilateral touches the circle at point P Q R S To prove : AB+ CD= AD+ BC Proof: from theorem 10.2 we get the tangents drawn from external point on circle are equal Hence, AP=PS .....1 BP= BQ.....2 CR=CQ........3 DR=DS....... 4 Adding 1, 2,3 and 4 we get AB+BP+CR+DR=PS+BQ+CQ+D'S AB+CD=AD+BC Hence proof.

Gaurav Seth 6 years, 10 months ago

Consider PT be a tangent to the circle from an external point P and a secant to the circle through P intersects the circle at points A and B, then PT² = PA × PB .

This property is used to solve the given question.

Let the two circles intersect at points X and Y. XY is the common chord.

Suppose A is a point on the common chord and AM and AN be the tangents drawn from A to the circle.

AM is the tangent and AXY is a secant.

∴ AM² = AX × AY …....(1)

AN is the tangent and AXY is a secant.

∴ AN² = AX × AY …..........(2)

From (1) and (2), we get

AM² = AN²

∴ AM = AN
