the answer is b:3
as Pythagoras theorem, the longer side equals the 2 shorter sides add together( squared)

root 18 - 3^2 = root 18 - root 9= root 9
and root 9=3

Answer: The correct option is (B) 3.

Step-by-step explanation: We are given to find the length of the leg s in the triangle shown in the figure.

From the figure, we note that

the given triangle is a right-angled one, where

length of the hypotenuse, h = √18 units,

length of one leg, p = 3 units

and

length of the other leg, s = ?.

From Pythagoras theorem, we have


h^2=p^2+s^2\\\\\Rightarrow (√(18))^2=3^2+s^2\\\\\Rightarrow 18=9+s^2\\\\\Rightarrow s^2=18-9\\\\\Rightarrow s^2=9\\\\\Rightarrow s=3.

Thus, the length of the leg s is 3 units.

Option (B) is CORRECT.
