Dear student,

I can help get you started.

circles

C is the centre of the circle on the right and B is the midpoint of the line joining the centres. By the symmetry angle ABC is a right angle. The length of CA is 5 cm and the length of BC is 1/2 (5√2) cm. Use Pythagoras theorem to find the length of AB.
