Question

In figure 1 triangle abc is circumscribing a circle find the length of bc

Answer 1

RA=AQ=4cm


RB=BP=3cm

AC=AQ+QC -> 11cm=4cm+QC
QC=7cm=PC
BP+PC=BC
3cm+7cm=10cm=BC

Answer 2

Answer:

Given, AR=4 cm

and, AR=AQ=4 (Tangents from the same point are equal)

CQ=AC−AQ=11−4=7 cm

CQ=CP=7 cm (Tangents from the same point are equal)

BR=BP=3 cm (Tangents from the same point are equal)

Now, BC=CP+BP

BC=7+3=10 cm
