#### Answer

The missing coordinates are:
$90^o: (0, 1)$
$60^o: (\frac{1}{2}, \frac{\sqrt3}{2})$
$45^o: (\frac{\sqrt2}{2}, \frac{\sqrt2}{2})$
$30^o: (\frac{\sqrt3}{2}, \frac{1}{2})$
$0^o: (1, 0)$

#### Work Step by Step

Using Figure 13 on page 579 of this book, the coordinates of the points indicated are:
$90^o: (0, 1)$
$60^o: (\frac{1}{2}, \frac{\sqrt3}{2})$
$45^o: (\frac{\sqrt2}{2}, \frac{\sqrt2}{2})$
$30^o: (\frac{\sqrt3}{2}, \frac{1}{2})$
$0^o: (1, 0)$
