Answer: A?

Step-by-step explanation: It shows all sides and diangles, if you were to draw lines with the letters, in different colors, like connect the dots? I don't know for sure and it's not the fanciest. I'm truly sorry, this answer just looks different from the rest. If the quadrilateral has 2 pairs of opposite, congruent sides, it is a parallelogram. If the quadrilateral has consecutive supplementary angles, it is a parallelogram? My second explanation belongs to it's rightful owner and I do not claim it as mine.

I have completed the first three parts of this question, but now need help to finish...I need to calculate the ratios of the 4 l

galben [10]

At first, we will find the lengths of LK, Lm, ON, OP, then use them to find the ratios between them

The rule of the distance is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

For LK

Since L = (3, 6), K = (1,5.33), then

$\begin{gathered} LK=\sqrt{(3-1)^2+(6-5.33)^2} \\ LK=\sqrt{4+0.4489} \\ LK=\sqrt{4.4489} \end{gathered}$

For LM

Since L = (3, 6), M = (5, 6.67), then

$\begin{gathered} LM=\sqrt{(3-5)^2+(6-6.67)^2} \\ LM=\sqrt{4+0.4489} \\ LM=\sqrt{4.4489} \end{gathered}$

For ON

Since O = (3, 2.59) and N = (5, 4.2), then

$\begin{gathered} ON=\sqrt{(3-5)^2+(2.59-4.2)} \\ ON=\sqrt{4+2.5921} \\ ON=\sqrt{6.5921} \end{gathered}$

For OP

Since O = (3, 2.59), P = (1, 0.99), then

$\begin{gathered} OP=\sqrt{(3-1)^2+(2.59-0.99)^2} \\ OP=\sqrt{4+2.56} \\ OP=\sqrt{6.56} \end{gathered}$

Now let us find the ratios between them

$\begin{gathered} \frac{KL}{LM}=\frac{\sqrt{4.4489}}{\sqrt{4.4489}}=1 \\ \frac{PO}{ON}=\frac{\sqrt{6.56}}{\sqrt{6.5921}}=0.9975\approx1 \\ \frac{KL}{LM}=\frac{PO}{ON}=1 \end{gathered}$

That means, Parallel lines intercept equal parts

By joining MP

We will have Triangle KPM

Since KL = LM ------- Proved using the distance formula

Since LQ // KP ------ Given

Then MQ = QP ------- Using the theorem down

The theorem

If a line is drawn from a midpoint of one side of a triangle parallel to the opposite side, then it will intersect the 3rd side in its midpoint (Q is the midpoint of MP)

What is the unknown angle measure in the triangle?

Black_prince [1.1K]

180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?

Y=-3x<br> y=6x-9 in substitution method

Anna007 [38]

The two equations given in the question are
y = - 3x
And
y = 6x - 9
Let us now substitute the value of y from the first equation to the second equation, we get
y = 6x - 9
- 3x = 6x - 9
-3x - 6x = - 9
- 9x = - 9
Multiplying both sides of the equation by -1 we get
9x = 9
x = 9/9
   = 1
Now let us put the value of x in the first equation, we get
y = - 3x
   = - (3 * 1)
   = - 3

The measures of the legs of a right triangle are 15 m and 20 m. Use the triangle measures and substitute the lengths for a and b

DochEvi [55]

Answer:

Step-by-step explanation:

We can use the Pythagorean theorem to determine the length of the hypotenuse

a^2 + b^2 = c^2

15^2 + 20 ^2 = c^2

225 + 400 = c^2

625 = c^2

Take the square root of each side

sqrt(625) = sqrt(c^2)

25 = c
