Question

A ladder 12 feet long leans against a tree trunk. The angle from the ground to the ladder is 36°. How far is the base of the ladder from the base of the tree?

Answer 1

@Red_Stevens Trig stuff huh...
It helps if you draw a diagram :)

Answer 2

So... let's put the known values up...
The ladder is 12 feet long so...

Answer 3

So what do you do from here?

Answer 4

Oh noes D:
The angle \(36^o\) is made by the
to the ground, here:

So the angle goes here:

Answer 5

Oh, so what do you do from there?

Answer 6

You know the trigonometric stuff... sine, cosine, etc?

Answer 7

Not really, I'm jumping up a grade and I'm trying to get caught up with some stuff. I know the basics though.

Answer 8

You know sines, cosines...
as in
SOH-CAH-TOA


\[\Large \sin\theta = \frac{opposite}{hypotenuse}\]\[\Large \cos\theta = \frac{adjacent}{hypotenuse}\]\[\Large \tan\theta =\frac{opposite}{adjacent}\]

Answer 9

Okay, so which one would I choose for this equation.
