Afield goal post in football is 3.33 yards above the ground. if a football player kicks the ball at a 10° angle in a straight line toward the goal post, what is the distance away, in yards, where the ball barely goes over the goal post?

In order to solve the given problem, use the tangent identity.
tan A = o / a
where a is the angle the football player kicks the ball
o is the height of the goal post
a is the distance of the ball from the yard

from the formula
a = o / tan A
a = 3.33 / tan 10
a = 18.89 yards
