11-34.

Use the vectors drawn at right to complete the parts below.

Rewrite each vector in both component and

form.Determine each vector’s standard angle.

Solve

. This will solve for the angle in the slope triangle for A.

Recall that the standard angle is measured from the positive-axis.What are

and ? Determine

. The double bars mean "the magnitude of". To calculate the magnitude of vector B, use the Pythagorean Theorem.
