Respuesta :

a2 = b2+c2 means
a squared=13squared- 5squared
=169-25
=144
=squared root of 144
=12

so your answer would be 12

The square of the hypotenuse is equal to the sum of the squares of other two sides. The missing side length of the right triangle is 12inches

Pythagorean theorem

The square of the hypotenuse is equal to the sum of the squares of other two sides

From the given parameters

Hypotenuse = 13in

Short leg = 5in

Determine the longest side

l² = 13² - 5²

l² = 169. - 25

l² = 144

l = 12in

Hence the missing side length of the right triangle is 12inches
