Does anyone know how to calculate r and theta from the question attached?

file.zip? Sounds legit.

What is the question? Is it from an exam paper or something?

oh god that question was disgusting, i got 6/75 for it in my mock...the radius is 1 from what i remember - the 2.5 minus the 1.5 on the sides. you need to draw in the semi-circle though. then you make some kind of triangle?

maybe finality will get her chance to shine here. :P
