What you need to know on this problem is that this ladder, just trying to make it look like it's a ladder, but not even that big a deal if it doesn't look like one.

But it's 25 feet long.
00:11
It's leaning against some building, a house, and this angle down here is 75 degrees.
00:19
Now, we're assuming that this house is at a right angle.
00:22
And so we have to do a right triangle trigonometry, which is, i'm sure you've heard the acronym sokatoa before.
00:31
Where the height of the house is going to be what i call x, and that's the opposite side.
00:36
And across from the right angle is always the hypotenuse.
00:40
So that's what these o's, h's, and a's stand for, opposite, hypotenuse, and this side that we actually don't care about is the adjacent...
