Using the equation a² +b² = c²
The lengths of a and b are always smaller than c.
We know that the hypotenuse is the longest side, making it c, meaning 3 and 5 are the opposite and adjacent sides.
Therefore, we substitute our numbers into the equation, 3² + 5² = c².
= 9 + 25 = c²
c² = 34
c = √34, which is equal to 5.83 (to the nearest hundredth)
