10-38.

Find the magnitude and standard angle $θ$ (where $0 \lt \theta \lt 2$) for each vector below.

Draw each vector starting at the origin and make a right triangle with the $x$-axis.

The vectors in both parts form special right triangles.

1. $−3\mathbf{i}+3\mathbf{j}$

1. $\langle 5,5 \sqrt { 3 } \rangle$
