Asked by Dunni
You are building a (rectangular) pool in your backyard. It measures 30m in the north-south direction and 25 meters east-west. (Some pool!) The bottom of the pool is a slanted plane so that it's 1m deep along the southern edge and 10m deep along the northern edge. (As I said, some pool!)
To build the pool you compute the angle of depression of a line from the southeast corner to the northeast corner. It is how many
degrees?

Draw a diagram.
assuming the line runs along the bottom of the pool, The angle is x, where
tan(x) = 9/√(25^2+30^2)
