Question

3.)
In fig. 1, if length of AB is 9 cm, then, find the length​

Answer 1

Answer:

4.5cm

Step-by-step explanation:

AC = CP

BC = CP

REASON.. TANGENTS FROM EXTERNSL POINT ARE EQUAL IN LENGTH

CP = CP

SO, AC = BC

SO, AC=4.5CM

AC = CP

THEREFORE, CP = 4.5CM

Answer 2

The length of CP is  4.5 cm

Step-by-step explanation:

given :AB = 9 cm

we have to find the length of CP

we know that the tangent drawn from the external point are equal in length

therefore

AC = CP ...(1)

similarly

CP = CB ..(2)

from 1 and 2

we get

AC = CB

AB = 9 cm

AB = AC + CB

AB = AC+ AC

9 = 2 AC

AC = 4.5 cm

and AC = CP = 4.5 cm

hence, The length of CP is  4.5 cm
