Answer:

15.16047 cm

Step-by-step explanation:

notice that the smaller triangles ratio is 3 : 5

so the bigger triangle's bottom side has length 13 cm

so lets multiply 13 by (3/5)

we get 7.8

we can just use pythagorean theorem to find AB

\sqrt{x} = 7.8^{2} + 13^{2}

15.16047 cm

Step-by-step explanation:

distribute
