This might be what it looks like.

Since we're dealing with an angle, its opposite side and it's adjacent side, we use TANGENT.

tan(angle)= \frac{opposite}{adjacent}

opposite=5
adjacent=2

By taking the angle, we use inverse.
angle= tan^{-1}  \frac{5}{2}

Then we can finally know the value by using your calculator. :)
