I need help with truth tables
Lerok [7]

The complete table of truth value for the composite proposition:

       p           q          ¬ q          p ∨ ¬ q            (p ∨ ¬ q) ⇒ q

       T           T             F              T                           T

       T           F             T              T                           F            

       F           T             F              T                           T

       F           F             T              T                           F                

<h3>How to fill a truth table with composite propositions</h3>

In mathematics, propositions are structures that contains a truth value. There are two truth values in classic logics: True, False. Composite propositions are the result combining simpler propositions and operators. There are the following logic operators and rules:

  1. Negation changes the truth value of the proposition into its opposite.
  2. Disjunction brings out "true" value when at least one of the two propositions is so.
  3. Conjunction brings out "true" value when the two propositions are so.
  4. Conditional form brings out "true" value when both propositions are true or only the consequent is true or both propositions are false.

Now we present the complete table of truth value for the composite proposition:

       p           q          ¬ q          p ∨ ¬ q            (p ∨ ¬ q) ⇒ q

       T           T             F              T                           T

       T           F             T              T                           F            

       F           T             F              T                           T

       F           F             T              T                           F

Question shown in pic attached!
m_a_m_a [10]

Answer: <B= 101, <C= 79, <D=101

Step-by-step explanation: all parallelograms have the diagonal angles equal so that is why <c=79. Parallelograms also have all angles equal to 360. so if you add <C, and <A you have 158. then you subtract that from 360 and you get 202. You then need to divide it by to to get the measures of angles B and D which are 101 each.
