Question

In figure $\Delta ABC$ is circumscribing a circle. Find the length of BC

• A. 8 cm
• B. 10 cm
• C. 12 cm
• D. 14 cm

Answer 1

The correct option is B 10 cm

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
