At this event, the crowd was confined to an area that was roughly the shape of a right triangle with side lengths that were approximately 300 feet, 350 feet, and 461 feet. Determine the appropriate dimensions of a similar space with 200,000 people. Show your work or explain your modeling. Determine the angle measures, in degrees, for the acute angles of the similar larger right triangle. Show your work or explain your modeling.
