D is the correct answer, first you have to write to you equations 1+ the absolute value of 2+ X equals nine and 1+ the absolute value of 2+ X equals -9 then you must subtract one from both sides

A triangle has one side that lies along the line y=1/4x and another that lies along the line y=-1/4x. Which of the following poi
mestny [16]

Answer:

We know that our triangle has one side along the line:

y = (1/4)*x

And other side along the line:

y = -(1/4)*x.

Now, we want to find the vertex.

And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.

Then we have:

y = (1/4)*x = -(1/4)*x

x = -x

The only solution to that equation is x = 0.

now we evaluate our lines in x = 0 and get:

y = (1/4)*0 = 0

y = -(1/4)*0 = 0

Then the lines intersect in the point (0, 0)

Then the vertex must be in the point (0, 0)

Triangle KNM is shown. Triangle K N M is shown. Angle M K N is 25 degrees. Angle K N M is 130 degrees. Angle N M K is 25 degrees
mars1129 [50]

Answer:

<h3>Two of the sides of triangle KNM are the equal</h3>

Step-by-step explanation:

From the triangle KNM, we can see that two of the angles M K N and Angle N M K are the same. If two of the angles are equal this means that two of the sides of the triangles are also equal. This type of triangle is known as an ISOSCELES TRIANGLE.

An isosceles triangle is a triangle that has two of its angles and sides to be equal.

Marta_Voda [28]
<h3><u>The value of the number is equal to 16.</u></h3>

7x + 8 = 120

<em><u>Subtract 8 from both sides.</u></em>

7x = 112

<em><u>Divide both sides by 7.</u></em>

x = 16
