Final answer:

To find the value of b in the expression 140° b, we can use the information provided in option (d). According to the information, 20₁ is 29° and 0₂ - 0₁ is 15.56°. Therefore, b is approximately 31.1°.

Step-by-step explanation:

To find the value of b in the expression 140° b, we need to determine what operation is being performed with b. From the given options (a), (b), (c), and (d), we can see that option (d) provides the necessary information to solve the problem. According to option (d), 20₁ = (2)(14.5°) = 29° and 0₂ - 0₁ = 30.05° - 14.5° = 15.56°. Thus, 29° is approximately equal to (2)(15.56°) which is 31.1°. Therefore, the value of b in the expression 140° b is approximately 31.1°.
