≈ 9.06

Explanation:

Using color(blue)" Pythagoras' Theorem "

which states " the square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides'

If hypotenuse = h and the other 2 sides are a and b then

h^2 = a^2 + b^2

here let a = 9 and b = 1 , then h^2 = 9^2 + 1^2 = 81 + 1 = 82

now h^2 = 82 rArr h = sqrt82 ≈ 9.06
