idont even know lol

anonymous · Answer

you're not supposed to, use a calculator =)
and make sure you work in degrees and not radians

anonymous · Answer

do i dive 505 and  33.69??

anonymous · Answer

leave the 505, i'm not sure how you got that
use a calculator and first calculate $\tan(33.69^\circ)$

anonymous · Answer

i got 0.666

anonymous · Answer

good. now we know $h = 15 \cdot \tan(33.69^\circ)$
so take that 0.666 and multiply by 15. what do you get?

anonymous · Answer

is it 9.9?
