You can put this solution on YOUR website! What is known?
First, the post makes a right angle with the ground
Then, if I were able to draw a straight line from the top of the post to
some other point on the ground, I would have a right triangle
The definition of the tangent of an angle is (opposite side) / (adjacent side)
h = height of pole in meters
so, tan 33.23 = h / 38
h = 38*tan 33.23
h = 38*.655
h = 24.895 m is height of pole
