Need help with this. I'm pretty sure it's just 4x-4=25 (since 30-25=5 and the triangles are similar), then you solve for x?
Just looking for some help here.
There are a few ways to think about this....
△JKL is similar to △MNP by AA similarity.
So each side of △MNP is some scale factor times the corresponding side of △JKL .
MN = JK * s where s is the scale factor.
30 = 25 * s
30 / 25 = s
So each side of △MNP is 30/25 times the corresponding side of △JKL .
MP = 30/25 * JL
4x - 4 = 30/25 * 20
4x - 4 = 24
I'll let you finish solving for x .
