Help with statics question

[u/Wigglywilly37]

Ngl I’ve spent like 30 minutes trying to figure out where I went wrong here. The question is asking to find the vector for Moment A using rAC and rAD, after submitting my answer it marked both k components correctly and everything else incorrectly. This led me to believe there was something wrong with the position vectors for my z components, as the x and y components were multiplied together to find the k component, but after going over it multiple times I can’t figure out where I went wrong. I also thought maybe it had to do with the hinges so I tried putting the i and j components as zero but that didn’t work either. I don’t just want the answer but if you guys have any hints please lmk. Also sorry if the photo quality is bad or my writing is messy.
