Determine the magnitude and direction of force F =240i + 310j + 750k.
For direction, determine θx, θy and θz.

Use the Pythagorean theorem to solve for the magnitude of F.
Calculate the magnitude of force F.
We next calculate the angle F makes with the x-axis.
We then calculate the angle F makes with the y-axis.
We finally calculate the angle F makes with the z-axis.
