## Homework Statement

If vector

a

is added to vector

b

the result is the vector

c

If

b

is subtracted from

a

the result is the vector

d

what is the magnitude of a?

what is the magnitude of b?

## Homework Equations

## The Attempt at a Solution

a + b = (7.00, 3.00)c

a-b=(-4.50,9.25)d

2a=(c + d)

(c+d/2) = a

a=(1.25,6.13)

b =c-a

b=(5.75,-3.13)
