Suppose we were to test the following argument to determine whether or not it is deductively valid (a case of semantic entailment): \neg \neg p, \neg \neg q\rightarrow r\models \neg (p\vee r) ¬¬p,¬¬q→r⊨¬(p∨r)¬¬p,¬¬q→r⊨¬(p∨r). the first step of using the truth-tree test is to setup the tree into what is called the ``stack''. which one of the following formulas would not be in the initial stack:

0.50 , 0.75

step-by-step explanation:

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

5.762159

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
