Question 1:

Given

0 \leq x \leq 720

solve

2 \tan x = 3

x = \begin{matrix} 56.3 & 236.3 \\ 416.3 & 596.3 \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 540

solve

4 \sin x = 3

x = \begin{matrix} 48.6 & 131.4 \\ 408.6 & 491.4 \end{matrix}

Question 4:

Given

0 \leq x \leq 180

solve

7 \sin x = 5

x = \begin{matrix} 45.6 & 134.4 \end{matrix}
