Which of the following is developed to result in the answer of 1?

5° + 9° ........ 13 - (7.42) ° .......... (-2.97)° ....... 3(8°)

To result in the answer of 1, we need to perform the operations in the correct order.

First, we calculate 5° + 9°, which equals 14°.
Next, we subtract 7.42 from 13, which gives us 5.58.
Then, we subtract 2.97 from 5.58, resulting in 2.61.
Finally, we multiply 3 by 8°, which equals 24°.

Adding all these results together, we have 14° + 2.61 + 24° = 40.61°.

Therefore, none of the given expressions developed as specified will give an answer of 1.

To find which of the given options results in the answer of 1, we can evaluate each option one by one and see if any of them equal 1.

1. 5° + 9° = 14° ⟶ Not equal to 1
2. 13 - (7.42)° ≈ 5.58° ⟶ Not equal to 1
3. (-2.97)° ⟶ Not equal to 1
4. 3(8°) = 24° ⟶ Not equal to 1

None of the given options results in the answer of 1.
