The problem is under trigonometry.
Let A be the point where the tip of 
Since the aim of
We now have a logical triangle ABC. The given data are AC = 8 meters, ACB = 90°, and ABC = 32.5%. By derivation, we get CAB = 57.5% by deducting the two known angles from 180° which is the sum of all angles of a triangle. Since all angles are known, we can use either the Law of Sines, Law of Cosines, or Law of Tangents. For this solution, we use the Law of Sines because it is the most simple among the three formulas.
Law of Sines: a / sin (A) = b / sin (B) = c / sin (C)
For the original problem, we will use b / sin (B) = c / sin (C)
In this solution, [side b] is AC (which is the unknown in this equation) and angle B is CBA or 32.5°, while [side c] is 8 meters and angle C is ACB or 90°.
AC / sin (32.5°) = 8 meters / sin (90°)
AC / 0.5373 = 8 meters / 1
AC = 0.5373 * 8 meters
AC = 4.2984 meters
Therefore, the distance between the ground and
