What is the remaining leg of a right triangle if the hypotenuse is 13 units and the other leg is 4 units?

Other side = 2    or

Step-by-step explanation:

Given  : The leg of a right triangle is 2 units and the hypotenuse is 4 units.

To find : What is the length, in units, of the other leg of the triangle.

Solution : We have given

Leg of a right triangle =  2 units.

Hypotenuse =  4 units.

By the Pythagorean theorem :

(Hypotenuse)² = (One leg)² + (other leg)².

Plug the values,

(4)² = (2)² + (other leg)².

16  = 4 +  (other leg)².

On subtracting both sides by 4

16 - 4 =  (other leg)².

12 =  (other leg)².

Taking square root.

Other side = 2  .

Therefore, Other side = 2   or
