Mathematics

1. The distance from a point on the ground to the
base of the tree is 18m.
The distance from a point on the ground to the
top of a tree is 20m. Calculate the height of the
tree.

Answer 1

8.7m

Explanation:

Let's say the height of the tree is h and apply pythagoras:

18² + h² = 20² =>

h = √76 ≈ 8.7m
