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, a² + b² = c².
Where,
a = 26 m
b = height of the building = h
c = 31 m
Plug in the values into the formula
Thus:
Subtract 676 from each side
Square both sides
(nearest tenth)
Avg equals = VALUE1 + VALUE2 / 2
so avg = 80+31 /2
avg = 55.5
