Question

\\i = \frac{11040}{1.732 \times 220 \times 0.89 \times 0.84}\\

Explanation:

Calculate the denominator

$$ 1.732 \times 220 \times 0.89 \times 0.84 \approx 284.9458 $$

Divide the numerator by the denominator

$$ I = \frac{11040}{284.9458} \approx 38.7442 $$

Round the final result

$$ I \approx 38.74 $$

Answer:

$$I \approx 38.74$$
