Answer:
[tex]x=6.2[/tex]
Step-by-step explanation:
Given triangle is right triangle so we can use trigonometric ratios to find the value of x.
[tex]\sin\left(\theta\right)=\frac{opposite}{hypotenuse}[/tex]
[tex]\sin\left(20^o\right)=\frac{x}{18}[/tex]
[tex]\sin\left(20^o\right)(18)=x[/tex]
[tex](0.34202014332566873304409961468226)(18)=x[/tex]
[tex]6.1563625798620371947937930642807=x[/tex]
[tex]x=6.1563625798620371947937930642807[/tex]
[tex]x=6.2[/tex]
Hence final answer is [tex]x=6.2[/tex]
