Answer:
B, the second image
Step-by-step explanation:
the pythagorean theorem states that a^2+b^2=c^2, where a and b are the base and height of the triangle and c is the hypotenuse of the triangle. Therefore, if you add the squares of a and b you should get the square of c.
In the first image, 9 + 36 =/= 64.
In the second image, 25 + 144 = 169, so the length of the hypotenuse is 13.
