Finding All Angles

Question 1:

Given

0 \leq x \leq 540

solve

7 \tan x = 4

x = \begin{matrix} 29.7 & 209.7 \\ 389.7 \end{matrix}

Question 2:

Given

0 \leq x \leq 540

solve

4 \cos x = 3

x = \begin{matrix} 41.4 & 318.6 \\ 401.4 \end{matrix}

Question 3:

Given

0 \leq x \leq 720

solve

5 \cos x = 3

x = \begin{matrix} 53.1 & 306.9 \\ 413.1 & 666.9 \end{matrix}

Question 4:

Given

0 \leq x \leq 720

solve

4 \sin x = 2

x = \begin{matrix} 30 & 150 \\ 390 & 510 \end{matrix}
