Answer:

The ladder makes an angle of 60 degree from the ground.

Step-by-step explanation:

Length of the ladder, L = 28 feet

distance of ladder, d = 14 feet

Let the angle formed with the ground is A.

According to the trigonometry

[tex]\cos A =\frac{d}{L}[/tex]

[tex]\cos A =\frac{14}{28}[/tex]

cos A = 0.5

A = 60 degree
