To solve this question, we can use the tangent. The adjacent leg to the angle will have a length of 9.3 and the opposite leg will have a length of 7.4

Using these, we can create an equation to solve for unknown angle (let it be x) using the tangent.

[tex]\tan(x)=\dfrac{7.4}{9.3}[/tex]

Take the inverse tangent, or arc tangent, on both sides.

[tex]x=tan^{-1}(\dfrac{7.4}{9.3})[/tex]
[tex]\approx 39[/tex]

Your answer is the first choice. I hope this helps! :)
