Use a calculator to approximate the measures of ∠A, ∠B, and ∠C to the nearest tenth of a degree. sin A = 0.96, tan B = 0.53, cos C = 0.44

To find each of the angles we must make the following clearances:
 For ∠A
 sin A = 0.96
 A = Asin (0.96)
 A = 73.7 degrees
 For ∠B
 tan B = 0.53
 B = Atan (0.53)
 B = 27.9 degrees
 For ∠C
 cos C = 0.44
 C = Acos (0.44)
 C = 63.9 degrees
 Answer:
 approximate measures of ∠A, ∠B, and ∠C are:
 A = 73.7 degrees
 B = 27.9 degrees
 C = 63.9 degrees
