Question

One leg of a right triangle has a length of 5 m. The other sides have lengths that are consecutive integers. Find these lengths.

The other leg is ____ m

The length of the hypotenuse is ____ m

Is my answer correct?

The other leg is 12 m
The hypotenuse is 13 m

Answer 1

Correct

The other sides :

x

and

x + 1

where x + 1 is the hypotenuse


So Pythagorean theorem:

( x + 1 ) ^ 2 = x ^ 2 + 5 ^ 2

x ^ 2 + 2 x + 1 = x ^ 2 + 25 Both x ^ 2 get cancelled

2 x + 1 = 25

2 x = 25 - 1 = 25 - 1 = 24

x = 24 / 2 = 12 m


hypotenuse

x + 1 = 12 + 1 = 13 m

Answer 2

It is 12

Answer 3

Hypo is 13
