1. The user is asking to confirm values for two variables, a and b. 2. The values given are a = 16.4 km and b = 079°. 3. Since no specific problem or formula is provided, we assume these are the final answers to a previous problem. 4. To confirm, ensure that a is a distance measured in kilometers and b is an angle measured in degrees. 5. Both values appear correctly formatted and reasonable for typical geometry or physics problems. Final confirmation: - a = 16.4 km - b = 79° (leading zero can be omitted as 79°)
