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:

s = 13 cm

Step-by-step explanation:

TP = TQ = 13 cm

1). TP = TA + AP = TA + AR = 13 cm

2). TQ = TB + BQ = TB + BR = 13 cm

Perimeter: $P_{TAB}$ = TA + AB + TB = (TA + AR) + (RB + TB) = 13 + 13 = 26

Semi-perimeter: $s_{TAB}$ = $\frac{1}{2} P_{TAB}$ = 13 cm
