x = \begin{matrix} 41.4 & 318.6 \\ 401.4 & 678.6 \end{matrix}

Question 2:

Given

0 \leq x \leq 540

solve

7 \cos x = 4

x = \begin{matrix} 55.2 & 304.8 \\ 415.2 \end{matrix}

Question 3:

Given

0 \leq x \leq 540

solve

4 \tan x = 2

x = \begin{matrix} 26.6 & 206.6 \\ 386.6 \end{matrix}

Question 4:

Given

0 \leq x \leq 720

solve

3 \cos x = 2

x = \begin{matrix} 48.2 & 311.8 \\ 408.2 & 671.8 \end{matrix}
