A vertical pole casts a shadow 20 meters. At the same times, a second vertical pole 8 meters high casts a shadow 32 meters long. find, in meters, the height of the first pole.
X : 20 where as 8 : 32 8 : 32 = 1 : 4
We make these ratio's into fractions...
1/4 = x/20
We use the proportion laws...
4x = 20
4x/4 = 20/4
x = 5
Thus the vertical pole's length is 20 meters
Guest had everything correct except the last sentence.....the height of the first pole = 5 meters instead of 20 meters
