Step-by-step explanation:
(4)
Using the sine ratio in the right triangle
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{9}[/tex], thus
Θ = [tex]sin^{-1}[/tex]([tex]\frac{7}{9}[/tex]) ≈ 51.1°
(5)
Using the tangent ratio in the right triangle
tanΘ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4}{5}[/tex], thus
Θ = [tex]tan^{-1}[/tex]([tex]\frac{4}{5}[/tex]) ≈ 38.7°
