Answer:
X = -4 and Y = 1 (sorry if wrong im only in 6th grade ;(
Step-by-step explanation:
X - 7Y = -11 ......(i)
5X + 2Y = -18 ........(ii)
multiply equation (i) by 5 we get 5X - 35Y = -55 ....(iii)
subtract equation (ii) from (iii)
we get -37Y = -37 ⇒ Y = 1
now put the value of Y from above in equation (i)
we get X = -4
R-4+3r-16=180
4r-20=180
4r=200
r=50

Answer: <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.
