(Choice C)

4, 7.5, 8.54,7.5,8.5

Step-by-step explanation:

We can use the Pythagorean Theorem to see if the side lengths will form a right triangle.

The equation for the Pythagorean Theorem is

a^2 + b^2 = c^2a  

2

+b  

2

=c

a, squared, plus, b, squared, equals, c, squared

where aaa and bbb are the lengths of the two legs of the triangle, and ccc is the length of the hypotenuse.

[How can I tell which side is the hypotenuse?]

Hint #22 / 5

Let's check each set of numbers:

\begin{aligned} a^2 + b^2 &= c^2 4^2 +\sqrt8^2 &\stackrel{\large?}{=} 24^2 16 + 8&\stackrel{\large?}{=} 576 24&\neq 576 \end{aligned}

,244, comma, square root of, 8, end square root, comma, 24 do not form a right triangle.

Hint #33 / 5

\begin{aligned} a^2 + b^2 &= c^2 5^2 + 5^2 &\stackrel{\large?}{=} 5^2 25+ 25&\stackrel{\large?}{=} 25 50&\neq 25 \end{aligned}
