Topic: Special Right Triangles
Kim and Yolanda are watching a movie in a movie theatre. Yolanda is sitting x feet from the screen and Kim is 15 feet behind Yolanda. The angle that Kim's line of sigh to the top of the screen makes with the horizontal is 30 degrees. The angle that Yolanda's line of sight to the top of the screen makes with the horizontal is 45 degrees.
How high is the top of the screen and how far is Yolanda from the screen?
