Finding All Angles

Question 1:

Given

0 \leq x \leq 360

solve

8 \sin x = 4

x = \begin{matrix} 30 & 150 \end{matrix}

Question 2:

Given

0 \leq x \leq 720

solve

5 \cos x = 4

x = \begin{matrix} 36.9 & 323.1 \\ 396.9 & 683.1 \end{matrix}

Question 3:

Given

0 \leq x \leq 540

solve

3 \cos x = 2

x = \begin{matrix} 48.2 & 311.8 \\ 408.2 \end{matrix}

Question 4:

Given

0 \leq x \leq 360

solve

3 \sin x = 2

x = \begin{matrix} 41.8 & 138.2 \end{matrix}
