As you already know, to get the inverse of any expression, we start off by doing a quick switcharoo on the variables, and then solve for "y", so let's do so,

$\bf \stackrel{f(x)}{y}=\cfrac{x-5}{3}\qquad inverse\implies \boxed{x}=\cfrac{\boxed{y}-5}{3}
\\\\\\
3x=y-5\implies 3x+5=\stackrel{f^{-1}(x)}{y}\\\\
-------------------------------\\\\
3(3)+5=f^{-1}(3)\implies 14=f^{-1}(3)$

To the nearest whole degree, what angle measure has a tangent of 2.0874?

kotykmax [81]

To find an angle measure, you would do inverse tan.

${ \tan }^{ - 1} (2.0874)$
You may need to hit the second button on your calculator to get this function.

Your answer turns up to be 64.402~~~~.

Rounded, the answer is 64 degrees.

Hope this helps!
