Question

Two circles with centres A and B are touching
externally A circle with centre c touches both
the circles externally, suppose AB=3cm BC=3cm.
and CA = 4cm Find the radii of the circles.​

Answer 1

Answer:

From the question,

AB = x + y = 3 ………. (1)

BC = x + y = 3 ………. (2)

CA = y + z = 4 ………. (3)

we have 3 equations and three unknowns,

by solving the equations, we get

x = 1 cm

y = 2 cm

z = 2 cm

hope it helps....
