tanX is 12/5.
Given:
In a right triangle,
The length of the side <em>XY</em> = 13.
The length of the side <em>YZ</em> = 12.
The length of the side <em>XZ</em>= 5.
The objective is to find tan <em>X</em>.
In a right angled triangle the largest side is always hypotenuse.
Sinec tan <em>X</em> is required to solve, then, the side <em>YZ </em>is opposite side and the side <em>XZ</em> is adjacent side.
By the trigonometric ratios, the value of tan <em>X</em> can be calculated as,
Hence, the value of tanX is 12/5.
