ong>Step-by-step EXPLANATION:

Given,

In right angle triangle ABC right angle at B,

Also given,

AB = 4cm, BC = 3cm, AC =?

Now,

According to PHYTHAGAROUS THEROM,

side^2 + side^2 = hypotenuse^2

AC^2 = AB^2 + BC^2

AC^2 = (4)^2 + (3)^2

AC^2 = (16) + (9)

AC^2 = 25

AC = √25

AC = √5×5 = 5

:. AC = 5 units.
