let me just say a fact- Face book had r o b o t s speak to each other to make sure the chat worked and then the r o b o t s started speaking in their own language and they understood each other so they had to shut that down- also Free points :) Happy Holidays

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
