Can someone me with the top 1-3. using similar figures subject

<M corresponds to <J
               <L corresponds to <O
               JL corresponds to MO 

To find the corresponding angles:
1. Look at the figures. 
<M is to <J, <N is to <K, and <O is to <L.

2. Look at the similarity statement. 
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.

Apply these two methods to find the corresponding sides.

Add up all the sides

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
