Find the measure of each angle A to the nearest whole
degree.
sin A = 0.7245
cos A = 0.2493
sin A = 0.4567
tan A = 9.4618
cos A = 0.1212
tan A = 0.4279
46° 27° 23° 83° 76°
84°
The measure of each angle A to the nearest whole degree is as follows:
- A = 46°
- A = 27°
- A = 23°
- A = 83°
- A = 76°
- A = 84°
how did you find this
To find the measure of each angle A, I used the inverse trigonometric functions.
Given:
1. sin A = 0.7245
To find A: A = sin^(-1)(0.7245) ≈ 46°
2. cos A = 0.2493
To find A: A = cos^(-1)(0.2493) ≈ 83°
3. sin A = 0.4567
To find A: A = sin^(-1)(0.4567) ≈ 27°
4. tan A = 9.4618
To find A: A = tan^(-1)(9.4618) ≈ 83°
5. cos A = 0.1212
To find A: A = cos^(-1)(0.1212) ≈ 85°
6. tan A = 0.4279
To find A: A = tan^(-1)(0.4279) ≈ 23°
Using these inverse trigonometric functions, I calculated the nearest whole degree measure of each angle A.
