Need help with a math question

Answer:
[tex]x =38.7\°[/tex]
Step-by-step explanation:
By definition, the tangent of a x-angle is defined as
[tex]tan(x) =\frac{opposite}{adjacent}[/tex]
For this case
[tex]opposite = 8[/tex]
[tex]adjacent = 10[/tex]
Therefore we have that
[tex]tan(x) =\frac{8}{10}[/tex]
[tex]x =arctan(\frac{8}{10})[/tex]
The answer is:
[tex]x =38.7\°[/tex]
