Answer:

$AC = \bf 4.13 \space\ cm$

Explanation:

Using Pythagoras's theorem:

$\boxed {a^2 = b^2 + c^2}$ ,

where:

a ⇒ hypotenuse (AC, ? cm)

b, c ⇒ the two other sides of the triangle (AB = 2.2 cm, BC = 3.5 cm),

we can find the length of AC.

AC^2 = AB^2 + BC^2

⇒
AC^2 = (2.2)^2 + (3.5)^2

⇒
AC = √((2.2)^2 + ((3.5)^2)

⇒
AC = √(17.9)

⇒
$AC = \bf 4.13 \space\ cm$
