Final answer:
To calculate the elevation at a point using slope distance and z angle, use the formula Elevation = Slope Distance * sin(Z Angle).
Step-by-step explanation:
To calculate the elevation at a point using slope distance and z angle, you should use the formula: Elevation = Slope Distance * sin(Z Angle). This formula calculates the vertical distance between the starting point and the point of interest. The sin function is used because the z angle represents the angle of elevation which is measured vertically.
