12. Draw an example of a scalene triangle. Describe the properties that make it scalene. 13. A man six feet tall casts a shadow ten feet long. At the same time a flag pole casts a shadow fifty feet long. Use similar triangles to determine the height of the flag pole. 14. Given the two similar triangles shown, list the measure of all six angles is A has a measure of 32 15. The two triangles are similar. Determine the length of side c' if a-10, c-25 and a'=35. A A' b B C C' 16. Find the sine of angle B. A B' 17. Find the three trigonometric ratios for angle B. B b 2 B C 5 18. To the nearest degree, find cos G) 19. An airplane on short final approach is 50 feet above the numbers on one end of the runway. On the other side of the runway, a distance 3000 feet away, is a man observing the landing. What is the angle of elevation to the plane at this instant? 20. A telephone pole that is 35 feet long has fallen against a tall building during a storm. From the sidewalk up to where the pole is leaning against the building is 20 feet. What angle does the telephone pole make with the side of the building? (To the nearest degree) 12.
