The letter “x” is often used in algebra to mean a value that is not yet known. It is called a “variable” or sometimes an “unknown”. (Hope this answer is help full)

Answer:

25

Explanation:

Given is a right angled triangle.

So by Pythagoras theorem:


{x}^(2) = {24}^(2) + {7}^(2) \\ \\ {x}^(2) = 576 + 49 \\ \\ {x}^(2) = 625 \\ \\ x = \pm √(625) \\ \\ x = \pm \: 25 \\ \\ \because \: x \: can \: not \: be \: - ve \\ \\ \therefore \: x = 25
