How do I solve the equation 10cos(x)=12sin(x) and what is the value of x? It is only part one of the question!! :P

Think of it as 10 times cos(x) and 12 times sin(x) and manipulate it like a regular algebaic equation to get to a form to allow you to find x off a trig chart.

I hope you, zabuzan, know your formulae, specially here,

\frac{sin(x)}{cos(x)} = tan(x)
