Pi is 3.14
1st # is 3.13
2nd # is 3.15
These numbers are irrational because pi=infinity
( I am not exactly sure if this is right so don't blame me if you get this wrong, I just tried to help.....) :T
It appears that the Pythagorean theorem can be applied to this problem
(distance to shadow)² = (height of building)² + (length of shadow)²
(38 m)² = (height of building)² + (28 m)²
660 m² = (height of building)²
Then the height of the building is
height of building = √660 m ≈ 25.7 m
The correct answer is 30cm

2x = 0
x = 0
The solution set is:
S={0}
