Question

PT is a tangent to
a circle with center‘0’
OT = 5cm, TP = 12 cm
then find
(1) OP
(2) which theorem have
you used ?​

Answer 1

Answer:

Correct option is

B

34 cm

Given PT=30cm

OT is the radius of a cicle

therefore OT will be half of given diameter

OT = 16cm

∠OTP = 90

∘

(tangent is perpendicular to radius at point of contact)

now apply pythoguras theorem to

OP
