The length of side AC = 5 units
Missing sides of a right triangle can be solved using the Pythagoras theorem
From the given question
Length of side AB = 3 units
Length of side BC = 4 units
The length of side AC is calculated below
[tex]AC^2=AB^2+BC^2\\\\AC^2=3^2+4^2\\\\AC^2=9+16\\\\AC^2=25\\\\AC=\sqrt{25}\\\\AC=5[/tex]
Therefore, the length of side AC = 5 units
