Question

Can someone please help me?

Answer 1

Answer: 31.5 feet

Explanation:

By using this information, we can create a triangle, with the hypotenuse being 39, and the first leg being 23.

Using the pythagorean theorem (a²+b² = c²)

23² + b² = 39²

529 + b² = 1521
1521 - 529 = b²

b = ≈ 31.5 feet
