a swimming pool is 3ft deep in the shallow end. The bottom of the pool has a steady downward drop of 12° toward the deep end. if the pool is 50 feet long , how deep is the end?
We can use the tangent to solve this.......we have
tan(12) = [d ] / 50 where d is the depth of the deep end [less 3 ft] rearrange
50 tan(12) = d = about 10.63 ft
However....we must add 3 ft to this = about 13.63 ft
