Question

Can i get the answer ASAP

Answer 1

Explanation:

If two triangles are similar, the ratio of the area of the triangles is proportional to the squares of its corresponding sides.

area of ΔJKL/area of ΔLMN = (JK)²/(NM)²

`(392)/(8)=((35)^(2))/((NM)^(2))\\\\49=((35)^(2))/((NM)^(2))\\`

Cross multiply,

49*(NM)²= 1225

`(NM)^(2)=(1225)/(49)\\\\(NM)^(2)=25\\\\NM=√(25)\\\\`

NM = 5 cm
