Answer 1

10.08

Explanation:

In
`\triangle ABC,\: m\angle ACB =90\degree`

`\implies \triangle ABC` is a right triangle, in which side AB is hypotenuse and sides AC and BC are mutually perpendicular.

By using Pythagoras theorem:

`AC^2 = AB^2 - BC^2 \\ \\ = {(11)}^(2) - {(4.4)}^(2) \\ \\ = 121 - 19.36 \\ \\ = 101.64 \\ \\ \implies \: AC= √(101.64) \\ \\ \huge\implies \: \red{AC=10.08}`
