M1 Help! Urgent!!!

draw a picture... first line going north length 300,

second line going northeast starting at the top of the other line length 40. the third side of the triangle gives you the answer.

That seemed to be the logical approach from my point of view (assuming that you are basically talking about pythogoras, right?)
So I did it and I got 302.65 (2dp) answer, but my teacher's answer states that it should be 329.5... Am I missing something or is his answers wrong?

it won't be a 90° triangle so Pythagoras won't be much use.

Oooohhhhhh.....

So... That's because the crosswind is north-east, right?
So do I use Sine rule/Cosine rule to solve this? I don't know any angles.. :/

mwhahaha but you do know an angle... north-east is a particular angle direction ?

..is that 45 degrees? (I don't know what I was thinking when I picked maths. xD All I can do is algebra. )

Yeah 45 degrees

Yeah 45 degrees

Can you post your working?

R^2=300^2+40^2-2x300x40xcos45(degrees)

Basically, 45 degrees isn't the angle to use, you should use 180-45 since the vectors effectively stack up

THANK YOU SO MUCH!!!!! (I would share my cookies with you!)
It works! That's almost like magic! Yay!
Thank you! ^^
