So as we look at this problem, we have a shallow end of our pool, three feet, and the deep end is seven.
00:07
It slopes at a rate of 5 .7 degrees, and it says the slope is constant.
00:14
So it's not shaped like a normal pool where there's a little plateau on each end, but we're just looking at this very basic sketch.
00:21
So we're trying to determine how long the pool is.
00:26
So what i might consider doing is something like this, where we sketch in our right triangle.
00:30
These are alternate interior angles, so i know this angle is 5 .7 degrees.
00:38
I know this distance here on my triangle is 4, because 3 plus 4, is 7, and i'm looking for the length of the pool, which in this case is x...
