Answer:
D
Step-by-step explanation:
To find the length of the hypotenuse, we use the Pythagoras’ theorem.
It states that the square of the hypotenuse equals the sum of the square of the two other sides.
So here, let’s say the hypotenuse is d.
d^2 = 6^2 + 5.5^2
d^2 = 36 + 30.25
d^2 = 66.25
d = √(66.25)
d = 8.14
