Question

A circle touches the sides of AA BC at D, E, F resActively
If AB 130m, BC = 12 cm and Acagem then
find AD.

please answer me ​

Answer 1

Answer:

We know that AD= AF

                         BD=BE

                          CE=CF

Let AD= AF=x

 BD=BE=y

CE=CF=z

Then x+y=12

y+z=8

x+z=10

On Solving above equation we get x=7,y=5,z=3

So AD=7
