Answer: 10 inches

Step-by-step explanation:

If the two triangles are similar, that means their sides are proportional to each other.

  • JK = 15
  • JL = 15 + 6 = 21
  • JM = 14

<em>The proportion would look like this:</em>

<em />\frac{JK}{JL} =\frac{JN}{JM}\\

<em>Substitute in the values:</em>

<em />\frac{15}{21} =\frac{JN}{14}

<em>Cross-multiply and solve for JN:</em>

<em />21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10

Answer:

10 inches

Step-by-step explanation:

JM=14<JL=21

And you know that JN=X<JK=15

You also know that JM=14>JN=x

KL=6 so NM=4

JM= (14) - NM (4)= 10

Hope this makes sense, and can help!

The total length of the wire needed to make this shape is 162cm

<h3>Perimeter of a triangle</h3>

The perimeter of a triangle is the sum of the external side of the triangle.

Given the following parameters

Length of one side of the outside shape = 24cm

The side length of the smaller triangle = 24/4 = 6cm

The perimeter of the smallest triangle  3(6) = 18cm

The perimeter of the smaller triangle (at the middle) = 12(3) = 36cm

Total length of wire needed. = 3(24) + 3(18) + 36

Total length of wire needed = 72 + 54 + 36

Total length of wire needed = 162cm

Hence the total length of the wire needed to make this shape is 162cm
