Answer:
[tex]AC = \bf 4.13 \space\ cm[/tex]
Step-by-step explanation:
Using Pythagoras's theorem:
[tex]\boxed {a^2 = b^2 + c^2}[/tex],
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.
[tex]AC^2 = AB^2 + BC^2[/tex]
⇒ [tex]AC^2 = (2.2)^2 + (3.5)^2[/tex]
⇒ [tex]AC = \sqrt{(2.2)^2 + ((3.5)^2}[/tex]
⇒ [tex]AC = \sqrt{17.9}[/tex]
⇒ [tex]AC = \bf 4.13 \space\ cm[/tex]
