A flagpole is 45 feet away from the school building. A 6-foot tall student stands 15 feet away from the building. What is the height of the flagpole?

Answer 1

6/30 proportion of his height to where he is standing
x/45 what we don't know and the distance of the flag pole
6/30=1/5 simplifying
x/45
1/5=x/45 setting them equal
x=9 if we sole we will get this
