add them.
using i,j coordinates
F= 260.6(sin30 j+ cos30 i)+ 21(sin-15 j+ cos 15 i)
then combine terms, and finally, use the right triangle..
Fnet= sqrt (forcei^2+forcej^2)
One student is pushing on a chair with a force of 260.6 N directed at an angle of 30 degrees above horizontal while a second student pushes on the same side of the chair with a force of 21.0 N at an angle of 15 degrees below horizontal. What is the magnitude, in N, of the sum of these forces?
how do i go about solving this question?

What do you mean by
Fnet= sqrt (forcei^2+forcej^2)
fnet= 380^2?
Fnet= sqrt (forcei^2+forcej^2)
fnet= 380^2?
