In a right triangle, if one side is 5 cm and the other is 12 cm, the hypotenuse will be _____?

7 cm

11 cm

13 cm

None of these

Using the Pythagorean theorem:

a² + b² = c²

where a and b are the lengths of the two sides, and c is the length of the hypotenuse.

Given:

a = 5 cm

b = 12 cm

Substitute the values:

5² + 12² = c²

25 + 144 = c²

169 = c²

Take the square root:

c = √169

= 13 cm
