A tree casts a shadow 6 m long when the sun is at an elevation of 70 degrees. A gardener wishes to fell the tree at ground level and needs to cut the trunk into 4 m lengths to cart it away. How many cuts must he make?
With x being the height of the tree, we have: =====>
Cross-multiplying, and solving for x will give you 16.484865 m.
Divide that by 4 to get the number of INTEGER-cuts. Drop the decimal.
