not him but are you just rolling with the fact blue angle is 90 deg? because it wont be if F1^2 != f^2 + other-side^2
and from the looks of just via drawing their modul length does not work that way.

Unless I'm reading it wrong and you just need to prove statement F1 = F*cos(theta) then I guess it's a given
