The answer is true because
(20) 3 = 10 (6)
60 = 60
X= 5y + 1
-2x + 9y = -1
-2(5y + 1) + 9y = -1
-10y - 2 + 9y = -1
-y - 2 = -1
-y = 1
y = -1
x + 5 = 1
x = -4
(-4, -1)
Vertical angles are congruent.
10x+60=30x-20
20x=80
x=4
All four angles add up to 360 degrees.
360-100-100=360-200=160
160/2=80
100, 100, 80, 80
Answer:
24÷2=12
