Finding All Angles

Question 1:

Given

0 \leq x \leq 180

solve

5 \tan x = 2

x = \begin{matrix} 21.8 \end{matrix}

Question 2:

Given

0 \leq x \leq 720

solve

5 \cos x = 4

x = \begin{matrix} 36.9 & 323.1 \\ 396.9 & 683.1 \end{matrix}

Question 3:

Given

0 \leq x \leq 360

solve

6 \sin x = 5

x = \begin{matrix} 56.4 & 123.6 \end{matrix}

Question 4:

Given

0 \leq x \leq 540

solve

5 \cos x = 4

x = \begin{matrix} 36.9 & 323.1 \\ 396.9 \end{matrix}
