hey, can someone please help me solve this equation? i really need help

Solution
For this case we can use the following definition:
[tex]\cot N=\frac{\cos N}{\sin N}[/tex]And from the figure given we have:
[tex]\cos N=\frac{12}{37},\sin N=\frac{35}{37}[/tex]And replacing we got:
[tex]\cot N=\frac{12}{35}[/tex]
