Answer:
[tex] \frac{ \sin(31) }{ \sin(59) } + \frac{ \cos(59) }{ \sin(31) ?} - 4 \times { \sin(45) }^{2} [/tex]
[tex] \frac{ \sin(31) }{ \sin(59) } + \frac{ \cos(59) }{ \ \cos(59) } - 4 \times {( \frac{1}{2} ) }^{2} [/tex]
[tex] \frac{ \sin(31) }{ \cos(31) } + 1 - 1[/tex]
[tex] \frac{ \sin(31) }{ \cos(31) } = \tan(31) [/tex]
