Can anyone me calculate ac, ad, and ec?

AC = sqrt(56^2 + 33^2) = 65cm

EC = sqrt(65^2 - 16^2) = 63 cm

to find AD 33-25 = 8

8^2 + 56^2 = AD^2

64 + 3136=3200^2

square root (3200) = 56.5685 round off to 56.6cm

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
