Answer:
23.3m
Explanation:
If you use the Pythagorean theorem to solve this, think of the tip of the building to the tip of the tip of the shadow as the hypotenuse then set it up like this, 30^2+x^2=38^2
subtract 30^2 from each side to get x^2=38^2-30^2
x^2=544
x=[tex]\sqrt{544}[/tex]
x=23.32380
x=23.3m
