What approximate value should come in the place of question mark (?) in the following question?

To solve the given expression and find the correct option, follow these steps:

- Begin with the right-hand side: \(14.99 + \frac{26.97 \times 179.97}{20.91}\).

- Calculate: \( \frac{26.97 \times 179.97}{20.91} \approx \frac{4852.03}{20.91} \approx 232 \).

- Total for the right side: \(14.99 + 232 = 246.99\).

- Now on the left-hand side, simplify the existing expression:

- \(454.95 - 229.99 = 224.96\).

- Let the equation be: \(224.96 + ?^2 = 246.99\).

- Solving for \(?^2\): \(?^2 = 246.99 - 224.96\).

- This implies: \(?^2 = 22.03\).

- Approximate value of ?: \(\sqrt{22.03} \approx 4.69\), closer to 5 but none of the options match exactly.

- None of the options seem directly correct without further context or potential assumptions.
