Homework Equations
Vector =ai +bj
The Attempt at a Solution
By using trigonometry, I found the following triangles : (-7.51, 2.74, 8)
(1.035, -5.91, 6)
So :
D=(1.035i-5.91j)-(-7.51i+2.74j)
D=8.545i-8.65j
I don't know why it isn't workng. I know that my answer isn't good. But I know that my steps are good.[/B]
