Answer:

16.9 m

Step-by-step explanation:

The diagram given that represents this situation is a right triangle.

The height of the building can be found using the pythagorean theorem, aĀ² + bĀ² = cĀ².

Where,

a = 26 m

b = height of the building = h

c = 31 m

Plug in the values into the formula

Thus:

[tex] 26^2 + b^2 = 31^2 [/tex]

[tex] 676 + b^2 = 961 [/tex]

Subtract 676 from each side

[tex] b^2 = 961 - 676 [/tex]

[tex] b^2 = 285 [/tex]

Square both sides

[tex] b = \sqrt{285} [/tex]

[tex] b = 16.9 m [/tex] (nearest tenth)
