Question

a circle touches all the four side of quadrilateral abcd if AB-6cm Bc-4cm Cd-8cm find the length of AD​

Answer 1

Answer:

We know that quadrilateral circumscribing the circle where tangents are equal

Let PQRS be a circle and ABCD be quadrilateral then

We know that tangent drawn from external point are equal so, AQ=AP ,BQ=BR,CS=CR,DS=DP add all these so, AB+CD= AD+BC. Let AD =X so from question 6+8=9+X so 14-9=X and X=5cm

hope it helps u buddy..

plls mark me as brainliest..
