anonymous · Answer

So, you're usually given one of the sides and asked to determine the rest, right? ^_^

anonymous · Answer

Yes :)  I know the hypotenuse equals 2 squared times the leg, right?

anonymous · Answer

You mean square root of 2, right? :/

anonymous · Answer

Um yes :s  I'm confused with all of it really O_o I've been trying to understand it for the past hour

anonymous · Answer

Well, you have a problem we can work on?

anonymous · Answer

Yeah, here's one :)

anonymous · Answer

f=√ ̅2 times 44 would be the first step? O_o

jhonyy9 · Answer

so you need calculi the side p ?

anonymous · Answer

yes ._. sorry I meant P* earlier,

jhonyy9 · Answer

than sin 45 = p/44

jhonyy9 · Answer

us this

jhonyy9 · Answer

hope you know the value of sin 45 ,yes ?

jhonyy9 · Answer

come on please cooperat anything

anonymous · Answer

Um 0.7071?

jhonyy9 · Answer

write every calculi please here step by step

jhonyy9 · Answer

but in the calculi for sin and cos 45 we us sqrt2 / 2

anonymous · Answer

yeah sorry I'm not following you O.o

jhonyy9 · Answer

so than 

sin 45 = p/44

sqrt2 /2 = p/44

p= 44sqrt2/2 = 22sqrt2

p=22sqrt2

jhonyy9 · Answer

ok ?

jhonyy9 · Answer

yw

good luck

bye

anonymous · Answer

Well I'm sure I'll understand it sometime. :) Thanks for your help though
