Question

What is the length of the hypotenuse of the triangle below?

Answer 1

Answer:

D

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square oh the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

h² = (9$\sqrt{2}$ )² + (9$\sqrt{2}$ )² = 162 + 162 = 324 ( take the square root of both sides )

h = $\sqrt{324}$ = 18 → D
