Answer:
23.24
Step-by-step explanation:
Pythagorean's theorem states that in a right angle triangle, the sum of the square of the opposite side with it's adjacent side is equal to the sum of the hypotenuse side.
Such that:
a^2 + b^2 = c^2 (where a and b are opposite and Adjacent sides respectively and c is the Hypotenuse side)
Note that, the Hypotenuse side is the longest side of the right angle triangle.
From the question:
6^2 + x^2 = 24^2
36 + x^2 = 576
x^2 = 576 - 36
x^2 = 540
x = √540
x = 23.24
