The horizontal viewing angle is the angle subtended by a straight line from each side of the screen to the seating position. THX Ltd., is a company founded in 1983 by George Lucas that develops audio/visual reproduction standards for movie theaters. According to THX, the viewing angle in a theater should be no less than 26 degrees and the best viewing angle seems to be around 45-50 degrees and towards the center. Suppose seat G11 has a horizontal viewing angle of 45°. This would be considered the best seat in the theater. 3. What is the measure of the arc the screen subtends? 4. If seats G8-G14 have been taken, where else could you sit that would provide a viewing angle of 45°? Explain.​
