Question

Find the value of x.

X =
Tell whether the side lengths form a Pythagorean triple.
o yes
no

Answer 1

X = 9.4

Explanation:

Pythagorean Theorem:

Formula: a² + b² = c²

• 9 x 9 = 81
• 3 x 3 = 9
• 81 + 9 = 90
• √90 = 9.48 (Rounded 9.5)

- A Pythagorean triple consists of any three positive integers.

Answer 2

x = √72 and yes, it forms a Pythagorean triple

Explanation:

a^2 + b^2 = c^2,

3 is a, x is b, anf 9 is c

3^2 + x^2 = 9^2

9 + x^2 = 81

Subtract 9 from both sides

x^2 = 72

x = √72

a Pythagorean triple is a^2 + b^2 = c^2, and this has it
