A Secant is drawn from a point P to a circle so that it meets the circle first at A, then goes through the center and leaves the circle at B. If the length of the tangent from P to the circle is 10 cm, and the radius of the circle is 6 cm, then the distance from P to A is?
Answer & explanation
Correct answer: option 1
OT ⊥ TP (∠OTP = 90°)
triplets = 6, 8, 10
OP = 8 cm
PA = OP - OA = 8 - 6 = 2 cm
