Finding All Angles

Question 1:

Given

0 \leq x \leq 360

solve

8 \cos x = 4

x = \begin{matrix} 60 & 300 \end{matrix}

Question 2:

Given

0 \leq x \leq 180

solve

2 \tan x = 4

x = \begin{matrix} 63.4 \end{matrix}

Question 3:

Given

0 \leq x \leq 720

solve

7 \tan x = 2

x = \begin{matrix} 15.9 & 195.9 \\ 375.9 & 555.9 \end{matrix}

Question 4:

Given

0 \leq x \leq 720

solve

8 \tan x = 6

x = \begin{matrix} 36.9 & 216.9 \\ 396.9 & 576.9 \end{matrix}
