how to find fnet? specifically 36.5 and theta 66

Answer 1

I think its the magnitude equation of the vector. Fnet = squrt(x^2+y^2) and tan(66)

Answer 2

the sum of the x-components of \( F_1, F_2, F_3\) is 28.3+0-43.3 = -15
and the sum of the y-components is 28.3+30-25= 33.3

so Fnet is the vector <-15, 33.3>
