Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion [tex]tan(18)=\frac{x}{20}[/tex] and we want to find the value of [tex]x[/tex].
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20
[tex]tan(18)=\frac{x}{20}[/tex]
[tex]20tan(18)=(\frac{x}{20} )(20)[/tex]
[tex]20tan(18)=x[/tex]
Step 2. use the reflexive property of equality: if [tex]a=b[/tex] then [tex]b=a[/tex]
[tex]20tan(18)=x[/tex]
[tex]x=20tan(18)[/tex]
Step 3. Using a calculator we get that [tex]tan(18)=0.325[/tex]. Replacing that value we get
[tex]x=20(0.325)[/tex]
x ≈ 6.5
We can conclude that the value of x is approximately 6.5
