Chapter 6.3, Problem 30PE

The Flatiron Building in New York City is said to have gotten its name because its cross-section resembles the shape of the household appliance of the same name. The perimeter of the building is bounded by Broadway, $5^{\text{th}}$ Avenue, and East ${22}^{\text{nd}}$ and ${23}^{\text{rd}}$ Streets. Using side lengths of approximately $87\text{ ft},190\text{ ft}$ , and $173\text{ ft}$ , determine the angle at the "point" of the Flatiron Building at the comer of 5th Avenue and East 23rd Street. Round to the nearest tenth of a degree.
