Question

In the figure, A ABC is circumscribes a circle.
AR = 4, BR = 3, AC = 11. Find length of BC.​

Answer 1

THE LENGTH OF BC IS 10CM

Step-by-step explanation:

LET AR=AP

{ BY TANGENT FROM A EXTERNAL POINT TO CIRCLE ARE EQUAL THEROM}

SIMILARLY BR=BQ THEN

AC =AP+PC

AC=AR+QC

AC=4+(11-4)

AC=4+7

THEN AGAINBY SAME THEORAM THE BC =BR+QC

BC=3+7

BC=10CM
