There

There is a stretched steel cable between the 3 columns. The height of the first column is 4 m, the height of the second is 3.5 m. The distance between the first two columns is 2.5 m, the distance between the second and third is 5 m. The heels of all three pillars stand in one line. What is the height of the third column?

Correct answer:

c =  2.5 m

Step-by-step explanation:

a=4 m b=3.5 m x=2.5 m y=5 m  (ab):x=(bc):y  bc=yx (ab) c=yx (ab)b c=yx (ba)+b=52.5 (3.54)+3.5=52=52 m=2.5 m
