# Triangles/ Coprime Integers watch

1. Can someone help me work this out?

The question is attached. I can work out angle BAC, but how do I go about working out a and b?

am I right in thinking that coprime means that both numbers are only divisible by 1?

And what level maths would you place this as? (GCSE,A-Level, etc) I'm curious because I haven't encountered a problem like this before.

Probably GCSE level.

Coprime means that the only factor they have in common is 1.

In this case it means that b/a is written in lowest possible terms of b and a.

Don't get me started. Your neglect of punctunation verges on being legendary.

Oh dear, there I go

And no full stop!
