Answer:

Θ ≈11.31°

Explanation:

the model is a right triangle with side opposite being the height and side adjacent the horizontal length , in relation to angle Θ , then

using the tangent ration

tanΘ =
(opposite)/(adjacent) =
(4)/(20) , then

Θ =
tan^(-1) (
(4)/(20) ) ≈ 11.31° ( to 2 dec. places )
