Triangles multiple choice!!

B

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABC

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

AB² + AC² = BC² , substitute values

5² + AC² = 13²

25 + AC² = 169 ( subtract 25 from both sides )

AC² = 144 ( take the square root of both sides )

AC = = 12

Since the triangles are congruent then corresponding sides are congruent, then

DE = AC = 12 inches → B

E is the answer to your question
