Question

Use a Pythagorean Triple to find x.

Answer 1

x = 51.

Explanation:

The triple you require is 17-15-8

We have x-45-24

- that is three times each number in the triple.

So x = 3*17 = 51.

Answer 2

x = 51

Explanation:

Using Pythagoras' identity in the right triangle.

x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )

x =
`√(2601)` = 51
