Question

4. Calculate the length of tangent from a point 15 cm. away from the centre of a circle of
radius 9 cm.

​

Answer 1

Answer:

Step-by-step explanation

r=9

distance of the point from radius =15

so by tangent properteis

adj=9

hyp = 15

so tangent length by pythogorous theorm is =

15^2 - 9^ = 144

root of 144 = 12

so tangent length = 12
