Question

A building casts a shadow that reaches10 ft. Out from the base of the building. The length of shade from the top of the building to the end of the shadow is 26 ft. How tall is the building?

Answer 1

24 ft

Explanation:

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

26^2 = 10^2 + length^2

676 - 100 = length^2

length = 576

find the square root

= 24
