Answer :

Let radius of circle with centre A be x, with centre B be y and with centre C be z

x + y = 5

⇒ y = 5-x …Equation(i)

y + z = 7

Putting the value of y from Equation (i) in the above equation

5-x + z = 7

⇒ z – x = 2 …Equation (ii)

z + x = 6 …Equation (iii)

Adding Equation (ii) and (iii) we get

2z = 8

⇒ z = 4 cm

Putting the value of z in Equation (iii) we get

4 + x = 6

⇒ x = 2 cm

The length of radius of circle with centre A = 2 cm
