Question

Triangles and Parallel Lines‼️ Help Please❓Find MJ? LM=12, NK=15, LN=20.

Answer 1

MJ = 9

Explanation:

Since JK is parallel to MN and MN intersects the 2 sides, then MN divides the 2 sides in proportion, that is

`(LM)/(MJ)` =
`(LN)/(NK)`, substitute values

`(12)/(MJ)` =
`(20)/(15)` ( cross- multiply )

20MJ = 180 ( divide both sides by 20 )

MJ = 9
