Answer:
The flagpole is 15 feet tall.
Step-by-step explanation:
The man casts a shadow that is 2/3 the length of his height. Because we know that the man and the flagpole are standing at the same time of the day, we can conclude that the shadow of the flagpole is 2/3 the length of the flagpole as well. Then, you would multiple 10(3/2) to get 15 as the height of the flagpole.
