To find x:
ON is parallel to LM
8x - 8 = 7x + 4
-7x -7x
1x - 8 = 4
+8 +8
1x = 12
--- ---
1 1
x = 12
8(12) - 8 = 7(12) + 4
96 - 8 = 84 + 4
88 = 88
------------------------------------
To find y:
NM is parallel to OL
x - 5 = 3y - 6
12 - 5 = 3y - 6
7 = 3y - 6
+6 +6
13 = 3y
--- ---
3 3
13/3 = y
Check:
12 - 5 = 3(13/3) - 6
7 = 13 - 6
7 = 7
C and D because I just know
Step-by-step explanation:
The equation is y = -x - 4.
Answer:
x=40
Step-by-step explanation:
so the angle opposite the 20º angle must also be 20º
this means that because 20º and 2 2x's are all on one straight line they must add up to 180
so 180=20+2*2x
160=4x
x=40
