would this pic be right ?

anonymous · Answer

yes thats right, you know the opposite side and you want to find the hypotenuse, so which of sin cos tan do you need to use?

anonymous · Answer

38 :) use formula sine33= opp21/hyp

anonymous · Answer

cool

anonymous · Answer

wouldnt it be hypotenuse/opposite since we dont know the hypotenuse

anonymous · Answer

hypotenuse/opposite gives us 1/sin not sin,

anonymous · Answer

not unless your doing scs or whatever is the opposite of sin lol. sin=opp/hyp

anonymous · Answer

38.55 is the hyp. so that would actually be 39. if that's what youre looking for

anonymous · Answer

so how do i write that out and solve then $$\sin 33=21/h$$ so how do i solve for this

@JamesWolf

anonymous · Answer

sin 33 = 21/h
h (sin 33) = 21
h = 21/sin 33
