Answer:

The angle complies with the state regulations.

Step-by-step explanation:

The angle of elevation is the angle \theta in the figure, and from trigonometry we find that

sin(\theta) = \dfrac{1.5ft}{25ft}

taking the inverse sine of both sides we get

\theta = sin^{-1}(\dfrac{1.5ft}{25ft})

which gives

\theta = 3.44^o

which is less than 5°, and therefore is well within the state regulations.
