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
Estimated answer is 4000 and actual answer is 3901
Step-by-step explanation:
- Step 1: Estimate 47 × 83 by rounding off to the nearest 10.
⇒ 47 ≈ 50 and 83 ≈ 80
⇒ 50 × 80 = 4000
- Step 2: Do the actual calculation of 47 × 83
