Let's start by the first column. The symbol ~ means negation. ~s will be the opposite of s.
Since s from top to bottom is T F T F, ~s will be F T F T(from top to bottom).
The second symbol that appears is ∧. This symbols means that p∧q is only true when both p and q are true. It needs to satisfy both of them.
From top to bottom, in the first line for ~s∧r we have ~s false and r is true, since ~s is false the combination is also false. For the second line, we have ~s true and r is true, since both are true the combination is also true. and in the last 2 elements, we have a false r which indicates both of them are also false.
This means, the second column will be F T F F(from top to bottom).
20 divided by 0 isn’t possible :)
Complimentary angels are angels that together add up to 90 degrees.
To find the measure of an angles compliment, simply subtract the degree you are given from 90.
90 degrees - 30 degrees = 60 degrees.
Hope this helps! :)
