The circumference involves 360 degrees.
60 degrees is one sixth of the circle (60/360)
So, one sixth of 72 is 12.
Answer:
-16 because the difference in between 10 and -4 is -16
6+6+6+8+8=31 that's the answer to your problem
Answer:
x=0.8, y=2.2 (0.8, 2.2).
Step-by-step explanation:
y+x=3
y=1.5x+1
-------------
1.5x+1+x=3
2.5x=3-1
2.5x=2
x=2/2.5
x=0.8
y+0.8=3
y=3-0.8
y=2.2
