Answer:

see explanation

Step-by-step explanation:

Subtract 4.2 from the height of the original 34 m, that is

height of remaining tree = 34 - 4.2 = 29.8 m ← hypotenuse of triangle

sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4.2}{29.8}[/tex], thus

Θ = [tex]sin^{-1}[/tex]( [tex]\frac{4.2}{29.8}[/tex]) ≈ 8° ( nearest degree )
