A50-foot flagpole is at the entrance of a building that is 300 feet tall. if the length of the flagpole's shadow is 30 feet at a certain time of day, how long is the building's shadow at that time? a. 75 feet b. 150 feet c. 180 feet d. 200 feet

First you will want to sketch out both of the situations. It should be two sketches, one for the flagpole and one for the building.

To solve this, you will want to create a proportion.

Flagpole height/flagpole shadow=building height/building shadow

Therefore, it should look like this:
50/30= 300/x

Solve for x:
50x=9,000
X= 180 feet

YOUR ANSWER IS C.
