Determine the reactions at the pin A and at the roller at B of the beam.

I honestly have no idea how to do this problem.
It gives the answers as...

Ax = 192 N
Ay = 180 N
By = 642 N

Please help.

As phanthom jay said above you have a roller joint at point B so you have just a vertical reaction force Rby since it is a pin joint at point A you have reaction forces Ray and Rax. The beam is inclined at 22deg
The 500N force is resolved vertically giving 500/cos22

therefore
Rax=0
SUM horizontal forces
Ray + Rby=500/cos22

SUM moment of forces about Point B
Ray.8 - Rax.3.33=800

so i get
Rax=0N
Rbx=0N
Ray=-100N
Rby= 1434.7N
