Rounding measures of sides to the nearest tenth Unit 7 Project Solve ABC using the given measurements. Round measures of sides to the nearest tenth and measures of angles to the nearest degree. 1. a = 7, A = 49° 2. A = 22°, c = 8 3. a = 7, c = 16 Rewrite each degree measure in radians and each radian measure in degrees. 4. 275° 5. 4 7Ï Find the exact value of each expression. Write angle measures in degrees. 6. cos(120°) 7. sec( ) 6 7Ï 8. Sin 1 ( ) 2 3 9. Arctan 1 10. Suppose Î is in standard position whose terminal side lies in Quadrant II. find the exact values of the remaining five trigonometric functions for Î for cos Î = . 2 3 State the vertical shift, amplitude, period, and phase shift of each function. Then graph the function. 11. y = sin θ 3 3 4 + 12. y = 3 cos [2(θ + 60°)] 1
