From the pythagoras theorem,
a² = b² + c²
where,
a = hypotenuse side
b = one of the other sides
c = the second of the other sides

Here, b = 5cm, c = 12cm and a = hypotenuse.

substituting,
a² = 5² + 12²
a² = 25 + 144
a² = 169
√a² = √169
a = 13.

Your hypotenuse is 13cm.

Your hypotenuse is 13 cm
I know be cause the square root of 169 is 13
I got 169 by doing 5 times 5 which is 25 plus 12 times 12 which is 144
144+ 25= 169
And the square root  of 169 is 13
Thn the hypotenuse is 13 cm
