Question

Find the value of x

Tell wether the side lengths form a Pythagorean triple

Answer 1

8.49 and No

Explanation:

C² - b² = a² (pythagorus rule rearranged for a²)

9² - 3² = a²

81 - 9 = a²

a² = 72

a = 8.49 and no they aren't a triple.

Answer 2

x = 6 root 2
Equation: square root of (9 squared - 3 squared)
I believe it is not a triple considering the answer is not a whole number but I could be wrong.
