For each equation, find two solutions $0° ≤ θ < 360°$, which make the equation true. You should not need a calculator.

1. $\sinθ =\frac { 1 } { 2 }$ 

   Hint (a):

   Draw and label a unit circle for each.

   Answer (a):

   $30°$ and $150°$

2. $\tan θ =\sqrt { 3 }$ 

   Partial Answer (b):

   $60°$

3. $\cos θ =\frac { \sqrt { 3 } } { 2 }$ 

   Partial Answer (c):

   $30°$

4. $\sin θ = -\frac { \sqrt { 2 } } { 2 }$ 

   Partial Answer (d):

   $225°$
