Question

The resultant of two forces is 50N. If the
forces are perpendicular to each other
and one of them makes an angle of 300
with the resultant, find its magnitude

Answer 1

sketch it
put resultant along x axis
F1 is then at -60 degrees (we want F1)
F2 is at +30 degrees
so
F1 cos 60 + F2 cos 30 = 50
F1 sin 60 - F2 sin 30 = 0
