|dw:1361201660763:dw|
which trig function uses the next.to (adjacent) and hypotenuse
tangent never looks at the hypotenuse; tan = over/nextto whats you next best one?
might help to write out the functions :) just as a review
Cosine
cosine is the winner !! now, cosine = next.to/ hypotenuse
with what is given that leaves us: cos(24) = 11/x can you solve for x?
manually?? or can i use a calculator?
youll need a calculator or table to determine cos(24) but just the setup would be useful. How would we move this equation around to solve for x?
I have NO CLUE, but the calculator is telling me 12.04
cos(24) = 11/x x = 11/cos(24) and yes, abt 12.04 is what i get as well http://www.wolframalpha.com/input/?i=11%2Fcos%2824%29
Oh ok thanks I understand now, and I have another question if you don't mind
if its a quick one, I have real job stuff that i have to attend to :)
kk hold on
What is the value of w to the nearest degree? Diagram (1 point) 25° 35° 40° 45° |dw:1361202248583:dw|
the idea is to find v in order to find w, right?
If this isn't quick you don't have to help, I don't want to waste your time
but yes
itll be quick enough, go ahead and write out the sin cos tan function for me so we can reference them
sin = Opposite/Hyp. cos = adjacent/ Hyp. tan= opposite/adjacent
lets name the parts to compare as well |dw:1361202408276:dw|
in my mind, over is the same as opposite :)
oh ok,
so, would you agree that the sine function works best for us on this one?
Yes
sin(65) = v/15 ; v = 15 sin(65) sin(w) = v/21, replacing the value of v we get sin(w) = 15 sin(65)/21 this make sense so far?
yes, I think i got it from here, Thanks
good :) keep in mind that to find w we need to do an inverse sin operation
I gotcha ;)
