Final answer:
To find the height of the building, set up a proportion using the lengths of the flagpole and its shadow. Cross multiply and solve for the unknown variable 'h'. The building is 32 feet tall.
Step-by-step explanation:
To find the height of the building, we can set up a proportion using the lengths of the flagpole and its shadow. The height of the building is the unknown variable, let's call it 'h'. The proportion can be set up as:
(height of flagpole) / (length of flagpole's shadow) = (height of building) / (length of building's shadow)
Plugging in the given values, we have:
8 ft / 17 ft = h / 68 ft
Cross multiplying, we get:
17h = 8 * 68
Simplifying, we find that h = 32 ft. Therefore, the building is 32 feet tall.
