Answer:
[tex]x=12\times \text{tan}(20^0)[/tex]
Step-by-step explanation:
From the figure attached,
Measure of an angle = 20°
Measure of the opposite side = x
Measure of the adjacent side = 12
By applying tangent rule in the given right triangle,
tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]\text{tan}(20^0)=\frac{x}{12}[/tex]
[tex]x=12\times \text{tan}(20^0)[/tex]
Therefore, equation to get the value of 'x' will be,
[tex]x=12\times \text{tan}(20^0)[/tex]
