Let's break down the problem:

- First, calculate 75% of 480:

- 75% of 480 = (75/100) x 480 = 360

- Equation becomes:

360 + (?)² = 5544

- Subtract 360 from both sides:

(?)² = 5544 - 360 = 5184

- Now, take square root:

? = v5184 = 72

- Review each option:

- Option 1: 70 70² = 4900

- Option 2: 89 89² = 7921

- Option 3: 72 v 72² = 5184

- Option 4: 69 69² = 4761

- Option 5: 78 78² = 6084

So, option 3 (72) is correct.
