Question

I given figure, triangleABC is circumscribing a circle, the length of BC is how much?

Answer 1

The length of BC is 10cm.

Explanation

In the given figure,

BQ=BP=3cm (As tangents arising from a point are always equal)

Similarly, AP=AR=4cm

Also, CR=11-4=7cm

CR=CQ=7cm

So, BC= CQ+BQ=7+3=10cm

Hope it helps.
