Question about Forces Using Unit Vectors

[imapeiceofwod]

The question is:

The total force exerted on the top of the mast B by the sail boats forestay AB and backstay BC is 180i-820j (N). What are the magnitudes of the forces exerted at B by the cables AB and AC?

I need some serious help with this question. Any help.

First off, this belongs in the homework forum. Secondly, there is nowhere near enough information in your post to begin calculating an answer.

 

[imapeiceofwod]

thats all the information I am given, i agree its not enough.

I would demand further data, were I in your situation. If this is a school question, as I have been led to believe, your teacher is either an idiot or planting a trap for you. At the very least, you need some sort of diagram to point out what the hell those boaty things are. I know what a mast is, but the rest is just a waste of alphanumeric symbols to me. Get a picture of the bloody set-up, with dimensions, and we might have a starting point.
If, on the other hand, this is some sort of gag being pulled upon you by some "friends", tell them to get stuffed and go grab a pop or coffee to chill out.

Do you know the angles that the cables AB and AC make?

 

[imapeiceofwod]

im given no angle. I am just given what i said in my first post. I made a diagram and that's about it. i just plotted the points on a graph and made drew my vectors.

and this is seriously a legit question my teacher gave me.

Without the angles, or any length information, the problem is impossible to solve as written.

Normally, one would write equations for the net force in both x and y directions.
