LMNP is a rectangle. Find the value of x and the length of each diagonal. LN= x and MP= 2x -8
loris [4]

Answer:

<h2>x = 8 (Verified) ✅</h2>

Step-by-step explanation:

If we visualize the figure, we can see that sides LN and MP are going to be parallel and of the same length.

So x = 2x - 8

Subtract x

0 = x - 8

x = 8

Check the answer

8 = 2(8) - 8

8 = 16 - 8

8 = 8 ✅

Which method would you use to prove that the two triangles are congruent?
Alona [7]

Answer:- AAS postulate


Explanation:-

  • AAS postulate tells that if two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

Given:- One angle and one side of a triangle is equal to the one angle and one side of the other triangle.

We see there is one more pair of equal angles as they are vertically opposite angles . [See the attachment]

⇒ there is a triangle where two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

⇒ The triangles are congruent [ by ASA postulate]

To use a compass to find the midpoint of a line segment, Rebecca draws two arcs of equal radius from each of the two endpoints o
DiKsa [7]
We are given a line segment with two points on each end. Rebecca draws two arcs with equal radius from each point. Now, the intersection of the two arcs is the midpoint of the line. This can be explained by the radius of the arcs. Since they are equal, meaning they have the same distance from each point. Thus, the midpoint of the line.

I need help with this question
Black_prince [1.1K]

Answer:

Step-by-step explanation:

The slope-intercept form is found by solving that equation for y.

If y-3=\frac{1}{2}(x-1) then

y-3=\frac{1}{2}x-\frac{1}{2} and

y=\frac{1}{2}x-\frac{1}{2}+3 and

y=\frac{1}{2}x-\frac{1}{2}+\frac{6}{2} so

y=\frac{1}{2}x+\frac{5}{2}

The answer you have chosen is the correct one!  Good job!
