Explanation: The given triangle is a right-angled triangle. This means that we can apply the Pythagorean theorem relating the lengths of the sides a follows: (hypotenuse)² = (first side)² + (second side)²
In the given we have: hypotenuse = 25 units first side = 24 units second side is the one we want to find
Substitute with the givens in the above equation to get the missing side as follows: (25)² = (24)² + (second side)² (second side)² = (25)² - (24)² (second side)² = 49
either: second side = -√49 = -7 > rejected as side length cannot be negative or: second side = +√49 = 7 > accepted
Hope this helps :)
