Right Triangle ProblemsThe calculator’s top row of keys providesbuilt-in solutions to square-up, drop, per-cent grade and slope problems.Square-up is computed from the valuesentered as length and width and is thediagonal length in a right triangle.Slope and percent grade are computedusing the values for width and depth (ordrop). Slope can be entered as either aratio of run per unit rise, or as a decimaldegree. Percent grade is entered as apercentage value. The following dia-gram shows the relationship of thesefeatures.Slope Ratio = Width:Unit DepthDepthPercent Grade = _____ x 100 %WidthDepthLength WidthSlope Ratio%–GradeSquare-upSlope AngleWidthUser’s Guide – 37
