Question

Please help me I think the answer is 12 cm .

Answer 1

You can find the value of the hypotenuse if you apply the Pythagorean Theorem, which is show below:

 h²=a²+ b² ⇒ h=√(a² + b²)

 h: hypotenuse (the opposite side of the right angle and the longest side of the triangle).

 a and b: legs (the sides that form the right angle).

 Then, you have:

 h²=a² + b²

 h²=12²+12²

 h=√ ((12)² + (12)²)

 h=12√2

 What is the lenght of the hypotenuse?

 The answer is: The length of the hypotenuse is 12√2
