Will Barrow wanted to know how tall the flagpole was in front of his school. To find its height, he drove a stake into the ground at the tip of the flagpole's shadow and recorded the angle of elevation at two different times during the day. He then measured the distance between the stakes. Will's data is below:
Stake
Time
Angle of Elevation
A
2:00 PM
