Quizplus · Accepted Answer

This is a right triangle, so we can use the Pythagorean Theorem to find the length of the hypotenuse (the side not given).

c^2 = a^2 + b^2

c^2 = 8^2 + 3^2

c^2 = 64 + 9

c^2 = 73

c ≈ 8.544 (rounded to the nearest thousandth)

Therefore, the best choice is D) 8.544 Using the Pythagorean Theorem, we can find the length of the hypotenuse: 
$c^2=a^2+b^2$
$c^2=8^2+3^2$
$c^2=64+9$
$c^2=73$
$c=\sqrt{73}$
$c\approx8.544$
