Answer:

≈ 9.2

Step-by-step 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.

let x be the third side ( hypotenuse ) , then

x² = 7² + 6² = 49 + 36 = 85 ( take square root of both sides )

x = \sqrt{85} ≈ 9.2 ( to the nearest tenth )
