Can someone help with this physics question PLEASE?

I'm confused on how you find the direction when adding two vectors?

Please show your working.

I take it both angles are in the horizontal plane - i.e. they are not pulling upwards at all?
How are these angle defined?

i.e. is one guy pulling 65deg to the right and the other 74deg to the left of the mule's facing?
A diagram would help here.

draw one vector as an arrow with its tail at the start; draw the second vector as an arrow with its tail at the first one's tip (but keep the arrow pointed along the actual vector's direction). If you have several vectors to add, just keep appending them like that, nexttail-to-lasttip. The total vector extends from first tail to the last tip.

Oh you've edited the question so my reply stops making sense :(
To the new questions: what lightgrav says ... add the vectors "head to tail".

I was guessing you knew this - and was working on common mistakes people make.
