Question

B
In the given figure, all the sides of a quad-
rilateral ABCD touch a circle with centre O.​

Answer 1

Answer:

AS and AP are tangents drawn from A to the circle

⟹AS=AP

Similarly

DS=DR,RC=CQ,QB=BP

AB=AP+PB=6

AP=6−PB

BC=BQ+QC=7cm

CD=CR+DR=4cm

AD=AS+SD=AP+RD

=(6−PB)+(4−CR)

=10–(PB+CR)

=10–(BQ+CQ)=10−BC

=10–7=3cm
