Question

Use a graphing utility to sketch the vectors and find the degree measure of the angle between the vectors.
u = 2i - 3j
v = 4i - 3j

Answer 1

How do you find the degree measurement?

Answer 2

Have you tried drawing an auxiliary line to divide the triangle (formed from the vectors and the x-axis) into 2 right triangles?

Answer 3

No, I don't know what to do from what I've posted.

Answer 4

Would it end up being x = 2 dividing the triangle? And how to you go about finding a degree measurement?

Answer 5

Draw this line:
From this, I think you can find the lengths of the sides of the triangle. with those lengths you can form trig ratios and use sin cos or tan to find the desired angle.
