Answer:

24 mm

Step-by-step explanation:

We use the Pythagorean theorem to solve this.  In the theorem, a and b are the legs of the triangle and c is the hypotenuse:

a² + b² = c²

a² + 7² = 25²

a² + 49 = 625

Subtract 49 from each side:

a² + 49 - 49 = 625 - 49

a² = 576

Take the square root of each side:

√(a²) = √576

a = 24
