MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Solve the right triangles for the unknown sides and angles. Round values to 1 decimal place if necessary. C b B 1) 1) B = 230, c = 17 A ) A = 67 B) A = 67: C) A = 67: D) A = 67 0 = 9.1 a = 15.6 a = 14.4 a = 6.6 b = 14.4 b = 6.6 b = 9.1 b = 15.6 Solve the problem. 2) Measurements taken 40 ft from the base of a flagpole show the angle of elevation to the 2) top of the flagpole to be 55.70 and the angle of elevation to the bottom of the flag to be 50.6 9. Determine the vertical width of the flag. Round to the nearest foot. Width 40 ft A ) 26 ft B ) 16 ft C) 8 ft D ) 10 ft
