Question

What is the angle 0 in the triangle below? (Hint:use the inverse trigonometric function.)

A. 33.6
B. 39.8
C. 0.83
D. 56.4

Answer 1

B. 39.8°

Step-by-step 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

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

Therefore, the correct option is option B.
