Yea I agree with what you did and that the first angle would be the same. Just not with using 4000N on the diagonals.

do you think you could help with a spring coefficient

I used a spring constant of 70 N/m for each spring.

Everything massless would be good. And everything frictionless. Those two things can always be made arbitrarily small in real life.
