Question

can anyone help me I'm confused?

Answer 1

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

The proportion would look like this:

$\frac{JK}{JL} =\frac{JN}{JM}$

Substitute in the values:

$\frac{15}{21} =\frac{JN}{14}$

Cross-multiply and solve for JN:

$21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10$

Answer 2

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!
