Hey /sci/
Need a little help with my math =/
I learned this stuff last year but im in a class called Math Analysis now and the teacher is bad.
Mind helping me out please? :>

A height of a vertical cliff is 450m. The angle of elevation from a ship to the top of the cliff is 23 degrees. The ship is x metres from the bottom of the cliff. Calculate the value of X.

All I need is like a picture of it, it goes with the SOHCAHTOA thing, but Im dumb so does my X go on the hypotenuse or the base?
