The sun is 25 degrees above the horizon. find the length of a shadow cast by a building that is 100 feet tall

SOH - CAH - TOA

We need to know the shadow length, which is adjacent to the angle we are given. We are also given the height of the building, which is opposite of the angle. Using both of these, we can find the shadow length:

tan 25 = 100/A
A = 100/ tan 25
A = 214.5 ft

You can use a calculater and divide the minutes by the $$, hope that you
