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, 5th Avenue, and East 22nd and 23rd Streets. Using side lengths of approximately 87 ft, 190 ft, and 173 ft, determine the angle at the "point" of the Flatiron Building at the corner of 5th Avenue and East 23rd Street. Round to the nearest tenth of a degree.
