which trig function uses the next.to (adjacent) and hypotenuse
 one year ago

amistre64Best ResponseYou've already chosen the best response.1
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 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?

amistre64Best ResponseYou've already chosen the best response.1
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
 one year ago

amistre64Best ResponseYou've already chosen the best response.1
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 :)

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

amistre64Best ResponseYou've already chosen the best response.1
itll be quick enough, go ahead and write out the sin cos tan function for me so we can reference them

zhane2015Best ResponseYou've already chosen the best response.0
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 :)

amistre64Best ResponseYou've already chosen the best response.1
so, would you agree that the sine function works best for us on this one?
 one year ago

amistre64Best ResponseYou've already chosen the best response.1
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?

zhane2015Best ResponseYou've already chosen the best response.0
yes, I think i got it from here, Thanks
 one year ago

amistre64Best ResponseYou've already chosen the best response.1
good :) keep in mind that to find w we need to do an inverse sin operation
