Engineering mechanics: static equilibrium of trusses.?

So this is the Free body diagram, I am tasked to find the forces at point A and B; forces acting on the joints

can you see if my answer is correct

Update:

my answer is shown below.

    Ax, Ay, Bx should all be 20 kN. You can find at least two by equating the sum of forces to 0 and then checking using momenta, or vice versa.

    Your work is illegible to me. Try for example imgur.com when you need to upload images with detail.

    This is my answer to the question. The answer about the forces acting on the points is on the left side, and the forces acting on the joints are on the right side (i,ii,iii,iv). I also checked if my answers would sum up to zero by adding the forces along the x and y-axis.
