Force problem Help?

A large boulder needs to be dragged to a new position. If pulled directly horizontally, the boulder would require 400 pounds of pulling force to move. We need to pull the boulder using a rope tied to the back of a large truck, forming a 15°angle from the ground. How much force will the truck need to pull with?

Thank you!!

    F*cos(15°) = 400 lbs

    F = 400 / cos(15°)

    F = 414 lbs
