Hi,



If the sun is 66 degrees above the horizon, 

find the length highlight_green%28x%29of the shadow cast by a building 70ft tall.

tan(66) = 70ft/x

 x = 70ft/tan(66)

this is way too easy. have you given it a go and got stuck?
here is a hint.
Imagine you are looking up at the sun. The angle between the flat ground you are standing on and the sun is 66 degrees. Now out of no where a 70 ft tall building is placed in front you, blocking the view of the sun and causing a shadow stretching from where the building is to your feet. Now what your question wants to know is what is the length of that shadow.
You have an angle and you have an opposite side and the Tangent of an angle is found using length of the opposite side/ length of the adjacent side
How that gives you a clue.
