Answer:
x = 7
Explanation:
From the figure, we can see the figure is a right triangle. To find the value of x, we need to apply the Pythagorean Theorem.
===============================================================
Solving :
⇒ (x)² + (24)² = (x + 18)²
⇒ x² + 576 = x² + 36x + 324
⇒ 36x = 576 - 324
⇒ 36x = 252
⇒ x = 252/36
⇒ x = 7
