zero vector as a resultant means that you end up where you started. So the vectors should form a triangle of lengths 7,24 and 25 I noticed that 7^2 + 24^2 = 25^2 so they will form a right-angled triangle with 25 the hypotenuse you can find one of the other angles by arctan(24/...

**Vectors/Calc**

Note: u,v,w,a,b are all vectors Given that u= xa + 2yb v= -2ya + 3yb w= 4a - 2b where a and b are collinear, find the values of x and y for which 2u - v =w
