Finding All Angles

Question 1:

Given

0 \leq x \leq 720

solve

4 \sin x = 2

x = \begin{matrix} 30 & 150 \\ 390 & 510 \end{matrix}

Question 2:

Given

0 \leq x \leq 540

solve

8 \cos x = 7

x = \begin{matrix} 29 & 331 \\ 389 \end{matrix}

Question 3:

Given

0 \leq x \leq 180

solve

4 \cos x = 3

x = \begin{matrix} 41.4 \end{matrix}

Question 4:

Given

0 \leq x \leq 720

solve

4 \sin x = 2

x = \begin{matrix} 30 & 150 \\ 390 & 510 \end{matrix}
