By the Pythagorean theorem:

AC = √(AB²-BC²) = √(9²-4²) = √(81-16) = √65 ≈ 8
CD = √(BD²-BC²) = √(5²-4²) = √(25-16) = √9 = 3
x = AC - CD = 8 - 3 = 5

Answer: 5

Answer:

x = √51

Step-by-step explanation:

The given figure is a right triangle.

Using the Pythagorean Theorem to find x

(Altitude 1)² + (Altitude 2)² = (Hypotenuse)²
(7)² + x² = (10)²
49 + x² = 100
x² = 51
x = √51
