ganeshie8 (ganeshie8):
look at the vectors in first option
can you find the magnitude of each of them ?
OpenStudy (sloppycanada):
first option -
vector a = sqrt2?
vector b = sqrt 34?

Or do I treat them as one vector? and
x1 = 1
x2 = 1
y1 = 3
y2 = 5
ganeshie8 (ganeshie8):
first option -
vector a = sqrt2?
vector b = sqrt 34?
this is corrrect
ganeshie8 (ganeshie8):
adding them gives you sqrt(2) + sqrt(34)
ganeshie8 (ganeshie8):
next, add the vectors first
ganeshie8 (ganeshie8):
familiar with adding two vectors ?
