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 · Answer

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

draw your setup, should amount to a right triangle

anonymous · Answer

Good so which one would we be using here? Think of it as a triangle

anonymous · Answer

cos?

anonymous · Answer

right so you just need to plug your lengths into the formula. cos4°=$$\frac{ x }{ 100 }$$

anonymous · Answer

x=65.3?

Is this a mulitple choice question?

anonymous · Answer

no

anonymous · Answer

Ok hold on and I'll check the work

anonymous · Answer

thank you

anonymous · Answer

Ok explain to me how you got that cause I got a different answer.

anonymous · Answer

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 · Answer

haha oh jeeze

anonymous · Answer

Ok recalculate and let me know what you got :)
