Computer Drawing A mathematics professor wanted to use a computer drawing program to draw a picture of a regular pen- tagon (a five-sided figure with sides of equal length and with equal angles). He first made a 1-in. base by drawing a line from (0, 0) to (1,0). (See the figure.) He then needed to find the coordinates of the other three vertex points. Use trigonometry to find them. (Hint: The sum of the exterior angles of any poly- gon is 360°.) (0, 0) (1, 0)
