A preseason game Tennessee Titans punter A.J. Trapasso hit the giant HD TV screen suspended above the field at the new Cowboys stadium. At the time of the punt A.J. was 30 yards away from the edge of the tv screen (the tv screen starts at the 40 yard line, and AJ was at the 10 yard line), and he kicked the ball straight at a 70 degree angle. How high is the video screen ?
