All angles are right angles or a triangle has 4 sides.a. Conjunction
b. Disjunction
c. Negation
d. Conditional

Answers

You know it's not a negation since nothing is being negated.

You know it's not a conditional because neither statement is reliant on the other to be true or false.

So, the answer must be a or b.

A conjunction implies there is an and which there is not. The solution then must be b. Disjunction, and it is indeed since disjunctions are the "or" statements of logic.

ABCD is a rectangle. Find the length of each diagonal.ac=2(5a+1) bd=2(a+1).

Answers

The length of the diagonal of the rectangle is d = 2

What is the diagonal of a rectangle?

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let the rectangle be represented as ABCD

Now , the diagonal of the rectangle is AC and BD

The measure of AC = 2 ( 5a + 1 )

And , the measure of BD = 2 ( a + 1 )

For a diagonal of a rectangle ,

The two diagonals of the rectangle will be same

So , the measure of AC = measure of BD

Substituting the values in the equation , we get

2 ( 5a + 1 ) = 2 ( a + 1 )

On simplifying the equation , we get

Divide by 2 on both sides of the equation , we get

5a + 1 = a + 1

Subtracting a on both sides of the equation , we get

4a + 1 = 1

Subtracting 1 on both sides of the equation , we get

4a = 0

a = 0

Now , substitute the value of a in measure of AC , we get

The measure of diagonal AC = 2 ( 5 ( 0 ) + 1 )

The measure of diagonal AC = 2

Hence , the measure of diagonals of the rectangle = 2

Rectangle diagonals are equal.

2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0

AC = 2(5a+1) = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2
BD = 2(a+1) = 2(0 + 1) = 2 × 1 = 2

Ansver: AC = BD = 2

slope=(1-7)/(10-1)=-6/9=-2/3
answer is A

Hello!

Answer:

A. -2/3

*The answer must have a fraction.*

Step-by-step explanation:

Slope: $(Y^2-Y^1)/(X^2-X^1)=(rise)/(run)$

$(1-7=-6)/(10-1=9)=(-6)/(9)=(-6/3)/(9/3)=(-2)/(3)$

Slope is -2/3

Answer: -2/3
