Answer 2

24

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 7² = 25² ( x is the missing leg )

x² + 49 = 625 ( subtract 49 from both sides )

x² = 576 ( take the square root of both sides )

x =
`√(576)` = 24
