Finding All Angles

Question 1:

Given

0 \leq x \leq 720

solve

6 \sin x = 3

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

Question 2:

Given

0 \leq x \leq 360

solve

4 \sin x = 3

x = \begin{matrix} 48.6 & 131.4 \end{matrix}

Question 3:

Given

0 \leq x \leq 720

solve

7 \sin x = 6

x = \begin{matrix} 59 & 121 \\ 419 & 481 \end{matrix}

Question 4:

Given

0 \leq x \leq 180

solve

7 \cos x = 4

x = \begin{matrix} 55.2 \end{matrix}
