Question

What is the length of the hypotenuse?

Answer 1

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let h be the hypotenuse, then

h² = 6² + 18² = 36 + 324 = 360 ( take the square root of both sides )

h = $\sqrt{360}$

   = $\sqrt{36(10)}$

   = $\sqrt{36}$ × $\sqrt{10}$

   = 6$\sqrt{10}$ → B
