Question

.Construct a tangent of length 4cm from a point which is at a distance of 5cm from the centre of the circle.
[hint:d?=r2+t?]​

Answer 1

Answer:

using Pythagoras theorem you can find the value of other side also.

Step-by-step explanation:

In right angled triangle AOB,

By Pythagoras theorem,

OB^2 = AB^2 + OA^2

(5)^2 = AB^2 + (4)^2

25 = AB^2 + 16

AB^2 = 25 -16

AB^2 = 9

AB = √9

AB = 3cm
