# Trigonometry Question

Watch
#1
Does anyone know how to solve this thing? Because. I've spent like 20 mins in a 42 mins test working on this problem and the only thing I've managed to find is the angle of the bottom triangle.... which I think was a waste of time since it didn't help me at all.

Anyway, sorry for rambling, the question was to find the length of line DP (it should be the one that is kind of more pronounced). I might have had a few details wrong but I'm pretty sure it was this one.

Do you have any more details you could provide, is P the midpoint of bottom line, anything that might help?

I'm pretty sure it's not the mid-point since the length 2cm isn't exactly large enough to extend to point D if point P is the midpoint but I could be wrong.

Is there another right angle somewhere?

I just remembered, there's one in Point D

Do you think this problem is even possible?

I assumed that one - no others?

Nope, those are the only ones unless you didn't count the one in the rectangle-ish corner near point P but I'm sure you already did

As it stands you do not have enough information to solve this problem

The 2cm sloping lines could be in a number of different positions - each of which gives a different answer

Yeah, maybe I'll try and post the full question once I get the paper back. Thanks for the help, btw
