Answer:

θ = 56.09°

Explanation:

Given that

h = 8.5 ft

speed ,u= 28 ft/s

We know that acceleration due to gravity g

g= 32.2 ft/s²

The maximum height h is given as

[tex]h=\dfrac{u^2sin^2\theta}{2g}[/tex]

Now by putting the values

[tex]8.5=\dfrac{28^2sin^2\theta}{2\times 32.2}[/tex]

[tex]sin^2\theta=0.69 [/tex]

[tex]sin\theta=0.83 [/tex]

θ = 56.09°

Therefore the angle will be θ = 56.09°
