Answer:
The triangle is not acute because 2² + 4² < 5².
Step-by-step explanation:
the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)
hypotenuse = 10
10/2 =5
so the answer should be 5sqrt(2), which I don't see as a choice
the first 5 is in the thousands place. The second 5 is in the hundredths place.
