Precalculus Prerequisites Review #7-Solving Right Triangle Problems Using Trigonometry 1. Use the diagram to identify each ratio. D 5 17 a. sin F = b. sin D' = 15 m 17 m 8 c. cos F 15 17 d. cos D= 8 m F 15 e. tan F=8 f. tan D E 2 Using the diagram from #1 above, calculate the measure in degrees of F. Sin F= 15 17 sin() = F = 62° 3. When a ladder leans against a wall, it reaches a height of 15 feet. The angle of incline is 60'. How far away from the wall is the base of the ladder? tan 60° = 173 15 1.73x = 15 15 x = 8.64 ft. 3. A kite is flying extended on 100 feet of string and is 30 feet high. What is the angle of elevation of the kite? 100 ft. 304 Sin x 30 100 Sin .3 Sin.3=x X = 17.5
