Answer:
Step-by-step explanation:
Using proportion...
length of barn length of tree
-------------------------------- = --------------------------------
length of barn's shadow length of tree's shadow
20 x
---- = ---
12 8
Using cross-multiplication...
20 x 8 = 12x
160 = 12x
x = 13 1/3 or 13.3333
The tree is 13 1/3 meters long.
The answer is true because there is infinite
numbers of points in the region.
The above statement is one of the Euclid’s five
postulates.
Euclid was a Greek mathematician also known as
the father of the geometry. The second postulate of Euclid is that a finite
straight line may be extended indefinitely in a straight line.
