Can someone help me with this truth table. I just don't understand how to do it.
RUDIKE [14]

An implication (p\implies q) is true if either the premise (p) is false, or both the premise and conclusion (p\text{ and }q) are both true, and false otherwise.

\begin{array}{c|c|c|c|c|c|c}p&q&p\implies q&\neg q&(p\implies q)\land\neg q&\neg p&(p\implies q)\land\neg q\implies\neg p\\T&T&T&&&&\\T&F&F&&&&\\F&T&T&&&&\\F&F&T&&&&\end{array}

Negation (\neg q) is straightforward; if a statement is true, then its negation is false, and vice versa.

\begin{array}{c|c|c|c|c|c|c}p&q&p\implies q&\neg q&(p\implies q)\land\neg q&\neg p&(p\implies q)\land\neg q\implies\neg p\\T&T&T&F&&F\\T&F&F&T&&F\\F&T&T&F&&T\\F&F&T&T&&T\end{array}

A conjunction (p\land q) is true if both premises are true, and false otherwise.

\begin{array}{c|c|c|c|c|c|c}p&q&p\implies q&\neg q&(p\implies q)\land\neg q&\neg p&(p\implies q)\land\neg q\implies\neg p\\T&T&T&F&F&F\\T&F&F&T&F&F\\F&T&T&F&F&T\\F&F&T&T&T&T\end{array}

Finally, by the rules of implication, we can fill the last column:

\begin{array}{c|c|c|c|c|c|c}p&q&p\implies q&\neg q&(p\implies q)\land\neg q&\neg p&(p\implies q)\land\neg q\implies\neg p\\T&T&T&F&F&F&T\\T&F&F&T&F&F&T\\F&T&T&F&F&T&T\\F&F&T&T&T&T&T\end{array}

What is the answer!!!!!?
posledela

Answer:

29 degrees

Step-by-step explanation:

Given

<D = 2x+8

<A = 122

The sum of the adjacent angle of the trapezoid is 180 degrees

<D + <A = 180

2x + 122 = 180

2x = 180-122

2x = 58

x = 58/2

x = 29 degrees

Hence the value of x is 29 degrees

Error Analysis Allie says JKL ~ XYZ<br> What is Allie's error?
Alex Ar [27]

Similar triangles may or may not have equal measures

Allie's error is that Allie did not state the similarity theorem

<h3>How to determine Allie's error </h3>

The statement JKL ~ XYZ means that:

Triangles JKL and XYZ are similar triangles

From the complete question, we have the following highlights:

  • Angles J and X have equal measures of 55 degrees
  • The side lengths of triangle XYZ are 3 multiplied by the corresponding side lengths of triangle JKL

The above means that, both triangles are similar by SAS or SSS

In Allie's statement, the similarity theorem is not stated

Hence, Allie's error is that Allie did not state the similarity theorem

Point b lies on the segment ac . Find the length of the segment ac, if ab=7.8 cm, bc=25mm. How many different solutions can this
mixas84 [53]

Given that B lies on segment AC and AB=7.8cm , BC = 25mm

Let us convert AB to mm by multiplying with 10 that is AB = 78mm

There are totally 3 possible  ways for B lying on segment AC.

Solution 1:- B lies in between A and C,

Then AC = AB+BC

               =78+25 = 103 mm

Solution 2:- B lies to the right of C like ACB.

Then AB = AC+CB

         78 = AC+25

         AC = 78-25 = 53mm

Solution 3:- B lies to the left of A like BAC.

Then BC = BA+AC

          25 = 78+AC

Since AC cannot be negative, this way is not possible.

Hence there are only 2 solutions possible.

If we are given that B lies on line joining A and C, then definitely B should lie between A and C.  That means nothing but solution 1. So only one solution is possible in this case.
