Answer:
25 mm
Step-by-step explanation:
we know that
Any right triangle must satisfy the Pythagorean Theorem
so
[tex]c^2=a^2+b^2[/tex]
where
c is the hypotenuse (greater side)
a and b are the legs (perpendicular sides)
substitute the given values
[tex]c^2=7^2+24^2[/tex]
[tex]c^2=625\\c=25\ mm[/tex]
