Answer:
Option (3)
Step-by-step explanation:
Let the unknown angle of the triangle measure x°.
By applying cosine rule in the right triangle,
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x) = [tex]\frac{33}{65}[/tex]
x = [tex]\text{cos}^{-1}(\frac{33}{65})[/tex]
x = 59.49°
≈ 60°
Therefore, option (3) will be the correct option.
