Question

Please answer the problem in the picture below.

Answer 1

D

Explanation:

in an isosceles triangle the 2 legs are congruent , both 6
`√(8)`

using Pythagoras' identity in the right triangle

the square on the hypotenuse h is equal to the sum of the squares on the 2 legs, that is

h² = (6
`√(8)` )² + (6
`√(8)` )² = 288 + 288 = 576 ( take square root of both sides )

h =
`√(576)` = 24

the length of the hypotenuse is 24 cm
