Concept explainers
One World Trade Center One World Trade Center (1WTC) is the centerpiece of the rebuilding of the World Trade Center in New York City. The tower is 1776 feet tall (including its spire). The angle of elevation from the base of an office building to the tip of the spire is . The angle of elevation from the helipad on the roof of the office building to the tip of the spire is .
(a) How far away is the office building from 1WTC? Assume the side of the tower is vertical. Round to the nearest foot.
(b) How tall is the office building? Round to the nearest foot.
