Because the triangles are similar, we can form the proportion 3/4 = 4/a

Cross multiply and solve for 'a'

3/4 = 4/a
3*a = 4*4
3*a = 16
3*a/3 = 16/3
a = 16/3
a = (15+1)/3
a = (15/3)+(1/3)
a = 5+(1/3)

The answer is choice B)

Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ

NNADVOKAT [17]

Answer:

The statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$ is a tautology.

Step-by-step explanation:

We have the following statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$

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:

$\lnot P$ , $\lnot Q$ , $\lnot P \land P$ , $\lnot P \land P \rightarrow Q$ , and $\lnot Q \lor Q$ with these you can construct the following truth table.
