Question

Triangles JKL and PML are similar. Find x.

Answer 1

Triangles JKL and PML are similar.

Corresponding sides are

JK and PM, or x and PM,

KL and ML,

LJ and LP.

Ratios of the corresponding sides should be the same.

JK/PM =LJ/LP

x/12 = 4/6

x=12*4/6=8

x=8

Answer 2

ΔJKL is similar to ΔPML

⇒ JK/PM = JL/PL

.

Solve x:

x/12 = 4/6

6x = 48

x = 8

.

Answer: x = 8
