    First thing I want to say is the Edco exam papers are awful and I can't use them. Every ****ing question I try to do is deferred material or I can't figure out whats geometry and whats trigonometry and apparently we don't have to do geometry anymore other than proofs/constructions or some such SO I DON'T KNOW WHAT TO DO ANYMORE. :mad:

    Now that I've got that out of my system.

    Has anyone figured out how to do that question? Its the one with the wingspan and the cabin that doesn't need any internal support. As far as I can see its a chord not an arc hence I don't see how to get the angle so I can find the radius.
