Small angle approximations

Hi,

Please can I have some help with this question.

I think i need the length CB but so far I have:


A/sin X = B/sin(3/4 Pi) = 1 / sin C

Any help finding CB please?

Why can't you say AC/sin (theta) = 1/sin C

We can find C as we know something about the angles in a triangle
oh right thank you = 180 or pi
