I normally understand this but i just cant get it 1. A cargo ramp leads up to the side of a building. The bottom of the ramp is 100 feet from the base of the building and makes an angle of 4° with the ground. Answer each of the questions and show all your work. Q) Find AC. The approximate length of the ramp. round to the nearest 10th of a foot.

I'm pretty sure for these you have to use tangent, cosine or sine.... do you know the formulas?
anonymous
  • anonymous
Sine = Opposite / Hypotenuse Cosine = Adjacent / Hypotenuse Tangent = Opposite / Adjacent

draw your setup, should amount to a right triangle

Good so which one would we be using here? Think of it as a triangle
anonymous
  • anonymous
cos?
anonymous
  • anonymous
right so you just need to plug your lengths into the formula. cos4°=\[\frac{ x }{ 100 }\]

  • anonymous
x=65.3?

Is this a mulitple choice question?

no

Ok hold on and I'll check the work
anonymous
  • anonymous
thank you
anonymous
  • anonymous
Ok explain to me how you got that cause I got a different answer.
anonymous
  • anonymous
OH! I see out mistake, we would use cos if we where looking so the length of the ramp. Here we are looking for height so it would use the sin formula :)
anonymous
  • anonymous
haha oh jeeze
anonymous
  • anonymous
Ok recalculate and let me know what you got :)

the question does ask for: the approximate length of the ramp.

  • anonymous
Wait no is says length..

\[cos=\frac{100}{ramp}\]

@amistre64 what did you get?

100 sec(4)

  • amistre64
alittle over 100
anonymous
  • anonymous
yea I got 99.756405026 using cos..
amistre64
  • amistre64
100/cos4 = 100.25 or so 100 cos4 = 99.75 :)
amistre64
  • amistre64
\[cos=\frac{next.to}{hyp}\] \[cos=\frac{100}{ramp}\] \[ramp=\frac{100}{cos}\] \[ramp=100~sec\]

What would i do if i wanted to find height?
