Question

PLZZZZ HELPPPPPPP!!!!

A person and a building cast a shadow at the same time of day. The person is 5.8 feet tall and cast a shadow of 3.2 feet.

The building casts a shadow of 28 feet.

Answer 1

Answer: The height of the building is 50.75 feet.

Explanation:

The ratio between the height of the object and the casted shadow must be equal for all the objects, as the angle at which the source if light impacts them is the same.

For the person, we know that it is 5.8ft tall, and the shadow is 3.2ft long.

The ratio will be: 5.8ft/3.2ft = 1.8125

Now, if H is the height of the building, and the shadow that the building casts is 28ft, we must have:

H/28ft = 1.8125

Now we can solve this for H.

H = 1.8125*28ft = 50.75 ft

Then the height of the building is 50.75 feet.
