Answer 1

Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in  the right triangle

sinΘ = $\frac{opposite}{hypotenuse}$ = $\frac{7}{9}$, thus

Θ = $sin^{-1}$($\frac{7}{9}$) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = $\frac{opposite}{adjacent}$ = $\frac{4}{5}$, thus

Θ = $tan^{-1}$($\frac{4}{5}$) ≈ 38.7°
