What is the length of the hypotenuse? What is the angle from north?

anonymous · Answer

90 degrees?

anonymous · Answer

I mean the angle from north to the resultant vector: the one that isn't given in the question. If it's a result of  eastward (90 degrees) and a southward (180 degrees) vectors, then it should be between 90 and 180

anonymous · Answer

so 90+180 would be 270

anonymous · Answer

270 degrees is west. A southerly wind isn't going to blow the boat west.

anonymous · Answer

umm...

anonymous · Answer

maybe....... 120?

|dw:1394036691917:dw| It's this angle here you're trying to work out. Also, you need to work out the length of the unknown side (which is a bit easier)
