what is the missing side in a right triangle if one leg measures 5 cm and the longest side measures 13 cm

The missing side is 12 cm length

Step-by-step explanation:

1. Let's review the information given to us to solve the case correctly:

Length of the longest side = 13 cm

Length of one leg = 5 cm

2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:

2nd leg² = Length of the longest side ² - Length of one leg²

2nd leg² = 13 ² - 5 ²

2nd leg² = 169 - 25

2nd leg² = 144

2nd leg = √144

2nd leg = 12 cm

The missing side is 12 cm length
