Answer:
6.67 cm
Step-by-step explanation:
PR = QR = 4 cm
A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
OR^2 = OP^2 - PR^2 = 5^2 - 4^2 = 9
OR = 3 cm
OPT angle is 90'
so TPR angle + OPR angle = 90'
OPR angle = tan-1 (3/4) = 36.87
TPR angle = 90 - tan-1 (3/4) = 52.13
PR /TP = cos (TPR angle)
TP = PR/ cos (TPR angle) = 4 / (3/5) = 20/3 = 6.67 cm
