Question

Q.
Find the length of the tongent drawn from a
point whose distance from othe Centre of a
circle is 25cm, given that the radios of
the circle is 7cm​

Answer 1

Step-by-step explanation:

Given:

Let the distance from the centre to the point be AC = 25 cm, here, A is the centre and C is the point.BC is the tangent whose length is to be found.AB is the radius of 7 cm.

To find:

Length of BC

Solution:

In triangle ABC,

By pythagoras theorem,

AC2 = AB2 + BC2

(25)2 = (7)2 + BC2

BC2 = 625 - 49

BC2 = 576

BC = 24

Therefore, length of BC is 24 cm.

Answer 2
