Two Vectors Three Here are two vectors:

a = (6.0 m)i - (3.0 m)j and b = (5.0 m)i + (5.0 m)j.

(a) What is the magnitude of a?

(b) What is the angle of a(relative to i)?

(c) What is the magnitude of b?

(d) What is the angle of b?

(e) What is the magnitude of a + b?

(f) What is the angle of a + b?

(g) What is the magnitude of b - a?

(h) What is the angle of b - a?

(i) What is the magnitude of a - b?

(j) What is the angle of a - b?

(k) What is the angle between the directions of b - a and a - b?

The angle between the two vectors is 180°.

The angle between the two vectors is 90°.

The angle between the two vectors is 60°.

The angle between the two vectors is 30°.

The angle between the two vectors is 45°.

The angle between the two vectors is 0°.

I have no idea how to figure out the magnitude, I thought I did but I only confused myself more. If someone can tell me how to find the magnitude how they want me to find it and also the angle, if would be appreciate. Thanks!
