Respuesta :

Answer:

B. 39.8°

Explanation:

Since the adjacent and opposite sides are given, we use tan ratio for the triangle.

Using tan ratio for the given triangle, we get

[tex]\tan \theta=\frac{\textrm{Opposite side}}{\textrm{Adjacent side}}\\\tan \theta = \frac{5}{6}\\\theta=\tan^{-1}(\frac{5}{6})=39.8[/tex]

Therefore, the correct option is option B.
