Please help me!!!!

Given cosx=12/13 and sinx=5/13 . What is ratio for ​ tanx ​ ?

$cos\ x=\frac{12}{13}\\x=arccos\frac{12}{13}=22.61986°$

$sin\ x=\frac{5}{13}\\x=arcsin\frac{5}{13}=22.61986°$

${\color{blue}tan\ x= \frac{sin\ x}{cos\ x}=\frac{5\cdot 13}{13\cdot 12}\color{blue}=\frac{5}{12}}\\ x=arctan\frac{5}{12}=22.61986°$
