Answer

17 blocks, -17$^o$ (i.e., 17$^o$ south of east).

Work Step by Step

The y-component of the displacement is -5 blocks and the x-component is 16 blocks. Use the Pythagorean theorem 3.4a to find the magnitude of the overall vector, and the definition of tangent, equation 3.4b, to find the angle. The vector has positive x-component and negative y-component, and points down and to the right.
