Question

In the given figure, three tangents TP, TQ and
AB are respectively drawn at the points P, Q and
R to a circle. Find the semi-perimeter of ATAB,
if length of TP is 13 cm.

Answer 1

Answer:

semi perimeter of ΔTAB= 13cm

Step-by-step explanation:

1/2(TA+AB+TB)

TQ=TB+BQ-1

TQ= TB+RB-2

Add 1 and 2

TA+AR+TB+BR

TA+AR=13

TB+BR=13

13+13=26

semi perimeter of ΔTAB

1/2*26=13cm
