8-44.

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

1. $\sinθ =\frac { 1 } { 2 }$

Draw and label a unit circle for each.

$30°$ and $150°$

1. $\tan θ =\sqrt { 3 }$

$60°$

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

$30°$

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

$225°$
