Round 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 7π Find the exact value of each expression. Write angle measures in degrees. 6. cos(­120°) 7. sec(­ ) 6 7π 8. Sin ­1 (­ ) 2 √3 9. Arctan ­1 10. Suppose Θ is in standard position whose terminal side lies in Quadrant II. find the exact values of the remaining five trigonometric functions for Θ for cos Θ = ­ . 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
