Finding All Angles

Question 1:

Given

0 \leq x \leq 180

solve

8 \sin x = 6

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

Question 2:

Given

0 \leq x \leq 180

solve

6 \cos x = 2

x = \begin{matrix} 70.5 \end{matrix}

Question 3:

Given

0 \leq x \leq 180

solve

2 \tan x = 7

x = \begin{matrix} 74.1 \end{matrix}

Question 4:

Given

0 \leq x \leq 720

solve

8 \sin x = 5

x = \begin{matrix} 38.7 & 141.3 \\ 398.7 & 501.3 \end{matrix}
