Multiple Choice

Construct an appropriate triangle to complete the table. $$\left( 0 ^ { \circ } \leq \theta \leq 90 ^ { \circ } , 0 ^ { \circ } \leq \theta \leq \frac { \pi } { 2 } \right)$$ $$\begin{array} { | c | c | l | l | } \hline \text { Function } & \theta ( \mathrm { deg } ) & \theta ( \mathrm { rad } ) & \text { Function Value } \\\hline \cos & 30 ^ { \circ } & & \\\hline\end{array}$$

A) ? $$\begin{array} { | c | c | c | c | } \hline \text { Function } & \theta ( \mathrm { deg } ) & \theta ( \mathrm { rad } ) & \text { Function Value } \\\hline \cos & 30 & \frac { \pi } { 3 } & \frac { \sqrt { 3 } } { 2 } \\\hline\end{array}$$
B) ? $$\begin{array} { | c | c | c | c | } \hline \text { Function } & \theta ( \text { deg } ) & \theta ( \text { rad } ) & \text { Function Value } \\\hline \cos & 30 & \frac { \pi } { 4 } & \frac { \sqrt { 2 } } { 2 } \\\hline\end{array}$$
C) ? $$\begin{array} { | c | c | c | c | } \hline \text { Function } & \theta ( \mathrm { deg } ) & \theta ( \mathrm { rad } ) & \text { Function Value } \\\hline \cos & 30 & 0 & 0 \\\hline\end{array}$$
D) ? $$\begin{array} { | c | c | c | c | } \hline \text { Function } & \theta ( \text { deg } ) & \theta ( \mathrm { rad } ) & \text { Function Value } \\\hline \cos & 30 & \frac { \pi } { 2 } & 1 \\\hline\end{array}$$
?E) ? $$\begin{array} { | c | c | c | c | } \hline \text { Function } & \theta ( \mathrm { deg } ) & \theta ( \mathrm { rad } ) & \text { Function Value } \\\hline \cos & 30 & \frac { \pi } { 6 } & \frac { 1 } { 2 } \\\hline\end{array}$$
