Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know that the hypotenuse squared is equal to the sum of its squared sides.
h^2=x^2+y^2
Here y=25 and x=8 so
h^2=25^2+8^2
h^2=625+64
h^2=689
h=26.25 ft
They obviously rounded to nearest whole foot.
So Carrie is correct in saying the ladder should be 26 feet.
