Question

question 10 of 10
what is the length of the hypotenuse of the triangle below?

Explanation:

Step1: Identify triangle type

It's a 45-45-90 right triangle (two 45° angles, one 90° angle).

Step2: Determine leg length

Legs are equal; given leg length: \(9\sqrt{2}\).

Step3: Calculate hypotenuse

In 45-45-90 triangle, hypotenuse = leg × \(\sqrt{2}\). So \(h = 9\sqrt{2} \times \sqrt{2} = 9 \times 2 = 18\).
