Answer: 41 and 139 degrees
Step-by-step explanation:
We know that
in a unit circle the radius is 1
therefore
[Length of a circumference]=2*pi*r------> 2*pi
if 2pi radians in a circle unit has a length of ------------> 2*pi
2pi/3 radians----------------------------> X
X=2pi/3
the answer is 2pi/3
9 times 9 = 81 6 times 6 =36 so 36 plus 18
Yes, that is correct because if you want to reduce it you divide 8 by 2 and 10 by 2 and you get 4/5
Boys are b
Girls are g
b + g = 120
2g = b
Substitute the second equation into the first
2g + g = 120
3g = 120
g = 40
Plug in g = 40 and solve for b
b + g = 40
b + 40 = 120
b = 80
There are 40 girls and 80 boys.
