Answer:
A
Step-by-step explanation:
supplementary agles add up to 180 degrees, so when you subtract 162 from 180, you get 18. Hope this helped :D
-10x-10 = -3x+4
+3x +3x
————————
-7x-10 = 4
+10 +10
————————
-7x = 14
then divide -7 on both side of the equal sign
you’ll get x=-2
then plug in -2 as x into one of the equations ( it doesn’t matter which one)
y= -10(-2)-10 = 20-10= 10
so y=10
All three of those angels are 98 degrees. F is supplementary, as the given angle and it must add up to 180. D is parallel to F. E is the same as D.
7/25 because you can divide everything. Y 3
