Determine the value of the trigonometric ratio.

Given,
The measure of side YZ is 21.
The measure of side XY is 20.
The measure of side XZ is 29.
Required:
The value of tanX.
The trigonometric ratio is calculated as,
[tex]tan\theta=\frac{side\text{ opposite to }\theta}{side\text{ adjacent of }\theta}[/tex]Substituting the values,
[tex]\begin{gathered} tanX=\frac{YZ}{XY} \\ tanX=\frac{21}{20} \end{gathered}[/tex]ence, the value of tanX is 21/290.
