R is the resultant coplanar-concurrent forces composing of P, T, F, and each Q acting on a body. Find the magnitude of the fourth force Q and its angle with respect to horizontal, if P = 840N directed downward to the left at 20 degrees with the vertical, T = 890N is acting to the right along the horizontal, F = 530N is up to the right at 45 degrees with the horizontal and R = 1300N acting downward to the right 30 degrees with the horizontal.
