Answer:
18.3 m
Step-by-step explanation:
The Pythagorean theorem is helpful here. It tells you the sum of the squares of the sides of the triangle is equal to the square of the hypotenuse.
h^2 + 31^2 = 36^2
h^2 = 36^2 -31^2 = 1296 -961 = 335
h = √335 ≈ 18.303
Rounded to the nearest tenth, the height of the building is 18.3 m.
