A tangent is drawn from a point 17 cm from the center of a circle of radius 8 cm. Find the length of the tangent.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 15 cm.
Distance of the point from center OP = 17 cm
Radius OT = 8 cm
Here, OT ⊥ PT then ∠OTP = 90°
Tangent length = √(172 – 82) = √(289 – 64) = √225 = 15 cm
