Question
The bottom of a rectangular pool rises at a constant 8 degree grade from the deeper end of 12 feet to the shallower end of 3 feet. how long is the pool?
Answers
scott
the depth change (9 ft) is opposite the 8º grade angle
the length is the adjacent side
tangent = opposite / adjacent ... adjacent = opposite / tangent
length = depth change / [tan(grade angle)]
the length is the adjacent side
tangent = opposite / adjacent ... adjacent = opposite / tangent
length = depth change / [tan(grade angle)]
