Construct a truth table for the disjunction a or b or c. compare with the following tables and select the correct one

Disjunction is a logical operation which forms compound propositions which are false only if all statements (disjuncts) are false. If at least on statement is true the result of disjunction is true. For three statements A, B and C the following table shows how it works (1 means true, 0 means false):

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
