Answer:

x ≈ 12.7

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + x² = 18²

2x² = 324 ( divide both sides by 2 )

x² = 162 ( take the square root of both sides )

x =
√(162) ≈ 12.7 ( to 1 dec. place )
