Using one of the above equations, you can find the value of x.
tan x = 84/13 => x = tan-¹(84/13)
x = 81.20°

Hope that helps

Answer:

[tex]m<X=81.20\°[/tex]

Step-by-step explanation:

we know that

In the right triangle XYZ

[tex]cos(X\°)=\frac{XY}{XZ}[/tex] -----> adjacent side to angle X divided by the hypotenuse

substitute the values

[tex]cos(X\°)=\frac{13}{85}[/tex]

[tex](m<X)=arccos(\frac{13}{85})=81.20\°[/tex]
