A 3D vector problem. Hard for me, easy for you

Ok i am studying for my final exam and i have run into a problem. I can't do this question (mainly because there are not enough measurements given to do it the way i normally would). So please, some help would be appreciated.

 

The 2.2 m uniform bar AB is supported by a ball-and-socket at A and two smooth walls at B, one in the x-y plane and one in the y-z plane. Determine the reaction components at A and B. Neglect the weight of the bar.

 

 

First off, i think it means x-z plane, not x-y plane. And secondly, I am really confused. Please help and explain thoroughly how to solve.

 

The answers are supposed to be

Ax = 1.9 KN

Ay = 2.21 KN

Az = 2.88 KN

By = 1.9 KN

Bx = 2.21 KN

 

THANK YOU SO MUCH!!!
