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
