Question

PLEASE HELP ASAP TRIGONOMETRY

Answer 1

Answer:

9). x = 36.9°

10). x = 18.3°

Step-by-step explanation:

9). By applying tangent rule in the given triangle,

   tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

   tan(x) = $\frac{9}{12}$

   x = $\text{tan}^{-1}(\frac{3}{4})$

   x = 36.87°

   x = 36.9°

10). By applying sine rule in the given triangle,

   sin(x) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

   sin(x) = $\frac{11}{35}$

   x = $\text{sin}^{-1}(\frac{11}{35})$

   x = 18.32

   x ≈ 18.3°
