Thread: cos (180 - theta) = 8

hello,

I'm working on a question involving resolving forces in equilibrium.

I don't know if I've been doing it right, but I've ended up with:

cos (180 - theta) = 8


Theta is an angle that I need to find.

Is there any way of manipulating the above in order to find theta?

maximum of is 1, so there is no way

Thanks for that useful information Dedust, I can definitely abandon that route then! I've actually realised now that I can actually tackle the question using good old Pythagoras, so simple, yet so useful!
