Question

at a given time of day, the ratio of the height of an object to the length of its shadow. is the same for all objects. if a 4-ft stick in the ground casts a shadow of 0.8ft, find the height if a tree that casts a shadow is 7.66 ft.

Answer 1

Stick -- Height 4 ft ---Shadow 0.8 ft

Tree---Height x ft --- Sadow 7.66 ft

We have a relation of equivalence, so the height of the tree x can be calculated as

`x=(7.66\cdot4)/(0.8)=38.3\text{ ft}`

The height of the tree is 38.3 ft
