Question

circles with centres A,B and C touch each other externally. If AB = 3cm, BC = 3cm ,CA = 4cm,then find the radii of each circle
​

Answer 1

Step-by-step explanation:

1. ab=3cm =X+y
2. BC=3cm=X+z
3. CA=4cm=z+X
4. divide 3equations
5. we get x+y+z=5......1
6. sub first three equations in 1
7. we get x=2,y=1,z=2

Answer 2

Step-by-step explanation:

name the circle as A,B,C and their radii as Ra, Rb and Rc.
