A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The simple statements from the statement given are:
,
,
, and 
This is the truth table.
Using the Pythagoras theorem
(sqrt 117)^2 = x^2 + 6^2
x^2 = sqrt117)^2 + 6^2
x^2 = 117 - 36 = 81
so x = 9 answer
You divide 2220 by 555 and you get 4 hours.
