Finding All Angles

Question 1:

Given

0 \leq x \leq 180

solve

5 \cos x = 3

x = \begin{matrix} 53.1 \end{matrix}

Question 2:

Given

0 \leq x \leq 180

solve

3 \tan x = 6

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

Question 3:

Given

0 \leq x \leq 360

solve

5 \cos x = 4

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

Question 4:

Given

0 \leq x \leq 180

solve

6 \tan x = 3

x = \begin{matrix} 26.6 \end{matrix}
