Question

Can anyone help me I'm confused?

Answer 1

10 inches

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!

Answer 2

Answer: 10 inches

Explanation:

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

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

The proportion would look like this:

`(JK)/(JL) =(JN)/(JM)\\`

Substitute in the values:

`(15)/(21) =(JN)/(14)`

Cross-multiply and solve for JN:

`21*JN=15*14\\JN=(15*14)/(21) =(210)/(21) =10`
