for first two forces,
Resultant1 = root(p^2 + 4p^2 + 4p^2 *costhetha).......................(1)
after increasing forces,
Resultant2 = root( (p+120)^2 + (4p)^2 + 2*4p*(p+120)costhetha).................(2)
and the direcn. is same therefore,
tanthetha = p/Resultant1...............(3)
and
tanthetha = (p+120)/Resualtant2.................(4)
solve the four eqns.
and get the values of R1 R2 thetha and p.
