Well we just need to add the 2 vectors, they add up nicely here

Looks like a right triangle doesn't it? *Pythagorea's*

aliza29faye · Answer

so you just add 200 and 150? or do you do a^2 + b^2 =c^2?

johnweldon1993 · Answer

The latter :)

$$\large Resultant = \sqrt{(150)^2 + (200)^2}$$

aliza29faye · Answer

so then the resultant is the direction or magnitude?

johnweldon1993 · Answer

That is the magnitude of the resultant...the direction comes next

johnweldon1993 · Answer

Now the direction, I'm not sure how precise they want you to be...idk if they want "north, south, east, west etc..." or the angle...but I'm going to assume just the previous

Well as we can see from my drawing...the resultant looks to be facing SW right?

aliza29faye · Answer

yep,

aliza29faye · Answer

my guess would be the angle
