Question

the tangent drawn to circle of radius 4 cm from a point at distance of 5 cm from the center. find length
​

Answer 1

Answer:

The Length of the Tangent is 3cm.

Step-by-step explanation:

Angle OAP = 90° [Radius perpendicular to Tangent]

.°. In ∆OAP:

>> AP² + OA² = OP²

>> AP² + 4² = 5²

>> AP² = 25 - 16

>> AP² = 9

>> AP = √9

>> AP = 3cm
