Answer 1

Answer:

Step-by-step explanation: join OQ and OR as they are radius of circle they are equal.

as tangents from an external point are equal

So AP=AS(tangent from A). .......1

DS=DR(tangent from D). .......2

AP=AS=5cm.......3

AD=23cm

AD=AS+SD

23=AS+SD

23=5+SD ........from 3

23-5=SD

18cm=SD

DS= DR=18cm.......from 2

CD=29cm

CD=DR+RC

29-18=CR

CR =11cm........4

As angle Cis 90° and OQ=OR

Therefore OQCR is a square.

So OQ=CQ=CR=OR=11cm

Therefore radius of circle is 11cm
