Let the radii of the circles be a, b, and c
Then we can write :
a+b = 7
b+c = 8
a+c = 9
By solving these equations we will get the values of a, b, and c as
a = 4 , b = 3, and c = 5
Then we can write :
a+b = 7
b+c = 8
a+c = 9
By solving these equations we will get the values of a, b, and c as
a = 4 , b = 3, and c = 5
