at a county fair truck pull, two pickup trucks are attached to the back end of a monster truck as illustrated in the figure. One of the pickups pulls with a force of 3000 pounds and the other pulls with a force of 2500 pounds with an angle of 60 degrees between them. With how much force must the monster truck pull in order to remain unmoved? (find the resultant of the two trucks)

If the above picture is correct, then F = 3000*cos(30) + 2500*cos(30)
or F = 5500 * cos(30) = ?
