Pretty pretty please if ur good at geometry!! Help a girl out!!

Answer:
Yes, They are similar by SSS PMK similar to LMQ.
Step-by-step explanation:
Similar triangles corresponding side lengths are in a proportion.
KM corresponds with MQ
PM corresponds with LM.
Set up this proportion.
[tex] \frac{km}{pm} = \frac{lm}{mq} [/tex]
[tex] \frac{15}{28} = \frac{21}{39.2} [/tex]
Cross multiply
[tex]588 = 588[/tex]
So the triangles ARE Similar.
