Max is in a control tower at a small airport. He is located 50 feet above the ground when he spots a small plane on the runway at an angle of depression of 27. What is the distance of the plane from the base of the tower? Round to the nearest foot.

I understand how to do it, but I don't know how to draw it out before I can start.

And would I use Sine, cosine, or Tangent? I think it's Tangent but I don't know.

yu have algebra 2a?

It's pre algebra

|dw:1370398086558:dw|  So for your 27 degrees, you have the adjacent and you want the opposite.  Tan is opposite over adjacent, so tan27 = x/50ft, solve for x.

A helpful way to know if it is Sine, Cosine, or Tangent is to use
SOH
CAH
TOA
_____
SOH = Opposite/Hypothesis    Sine
CAH = Adjacent/Hypothesis    Cosine
TOA = Opposite/Adjacent       Tangent
