Respuesta :

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.
