Х

Answer 1

x ≈ 14.87

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 = 10² + 11² = 100 + 121 = 221 ( take the square root of both sides )

x =
`√(221)` ≈ 14.87 ( to the nearest hundredth )
