NO LINKS!!!<br><br>Make a flowchart to show the two triangles are similar. ​
timama [110]

Answer: The flowchart is shown below.

Explanation:

Each box is a different statement. The reason for the statement is provided below the box. The arrows on the flowchart direct the flow of how the proof is laid out. Typically the flow is left to right, top to bottom, or a mix of both. This is to match the reading order of many western countries. Though I would imagine the flow is reversed for countries that read from right to left.

The structure of any type of proof is to start with what you are given. Then use the previously established, or previously proven, theorems to make your way to what you want to prove.

In this case, we start off with MN and KL being parallel line segments. This is shown by the arrows on MN and KL. Because the segments are parallel, we then can determine these two facts:

  • angle MNJ = angle KLJ
  • angle NMJ = angle LKJ

Both of those will have the reasoning of "corresponding angles theorem"

We have two pairs of angles which are congruent. This then directly leads to the triangles being similar. Refer to the AA (angle angle) similarity theorem for more information.

Feel free to use symbols in place of some words. For example, instead of saying something like "Triangle NMJ is similar to Triangle LKJ", you could write \triangle \text{NMJ} \sim \triangle \text{LKJ}

If you're curious what app I used to make the flowchart, the app is called "LucidChart". They have 3 options: 1 free and the other 2 are paid versions. I went with the free version and it worked just fine. But it's up to you which you prefer most.

Eduardwww [97]
First, add the integers to get 3. Then, add 2/3 and 3/5 by converting them into fifteenths, for a total of 19/15, or 1 4/15. Add these together to get 4 4/15 miles.

The variable y is directly proportional to the variable x. If y = 12 when x = 14, what is the value of x when y = 247
vlabodo [156]

Answer: 288.17

Step-by-step explanation:

y ∝ x

⇒ y = kx

substituting the given value of x and y , the equation becomes

12 = 14 k

therefore

k = 12/14

k = 6/7

The formula then becomes

y = 6/7 x

when y = 247, we have

247 = 6/7 x

6x = 247 x 7

6x =  1729

x = 1729/6

x = 288. 17
