A conveyor belt carries supplies from the first floor to the second floor, which is 12 feet higher. The belt makes a 60 degree angle with the ground. How far do the supplies travel from one end of the conveyor belt to the other? Round your answer to the nearest foot.

@maleena_1
cos
@563blackghost
Actually we would use sin becuase we know of the opposite and want to know of the hypotenuse side....|dw:1456097496298:dw| Now we insert this into the ratio of sin...
I don't get the ratio part
\(\huge\color{purple}{\sin(60)=\frac{12}{x}}\) We would divide by 12 since 12 is located as the numerator and we need the variable x as its self... \(\huge\color{red}{x=12\div\sin(60)}\) Note: When inputting this into your calculator make sure that your calculator is set to degree instead of radian mode....
\(\Large{\cos(x)=\frac{adjacent}{hypotenuse}}\) \(\Large{\sin(x)=\frac{opposite}{hypotenuse}}\) \(\Large{\tan(x)=\frac{opposite}{adjacent}}\) These are the three identities and their ratios...
I got a decimal? 0.866
That is incorrect.... did you place the problem in the calculator as shown... When inputting it would look like.... \(\Large{12/\sin(60)}\)
yes that is what I put in
And is your calculator set in degree mode?....to check look on you calculator for mode; then you would click it and find "radian" and "degree" in which you would click on "degree" and then leave the area...
yes it is degree
Well thats weird... O.o
how am I supposed to get the answer
Well you should get the total of 13.8564... which is the length of the conveyor belt distance... now do you need this in decimal or radical form?
I got it thanks
\(\Huge\cal\rlap{\color{red}{No~Problem!:)}}{\color{blue}{\;No~Problem!:)}}\) I hope your cal will work for future problems :)
