Answer:
Good day! Use trigonometry to define the formula.
Step-by-step explanation:

The height of the tree that the sun appears just over it top is 12 meters
The situation forms a right angle triangle.
The height of the tree is the opposite side of the triangle.
His distance away from the base of the tree is the adjacent side of the right angle triangle.
Therefore,
Using trigonometric ratio,
tan 32 = opposite / adjacent
tan 32 = h / 20
cross multiply
height of the tree = 20 tan 32
height of the tree = 20 × 0.6248693519
height of the tree = 12.4973870382
height of the tree ≈ 12 meters
