Question

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

Answer 1

Answer:

MJ = 9

Step-by-step explanation:

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

$\frac{LM}{MJ}$ = $\frac{LN}{NK}$, substitute values

$\frac{12}{MJ}$ = $\frac{20}{15}$ ( cross- multiply )

20MJ = 180 ( divide both sides by 20 )

MJ = 9
