N=0.5
1x0.5=0.5 which is less than 1 but greater than 0
It would still be 3 out of 12 since you put the original marble back in the bag
Answer:
i think you multiply them i could be mistaken
Ratio s 3:8
other one is x:12
3:8=x:12
3/8=x/12
times both sides by 12
36/8=x
4 and 4/8=x
4.5=x
4 and 1/2=x
J is answer
So the exterior angle of any polygons are 360 in total. since in the pic there r some interior angles, we need to 180 - interior to get the exterior angle. since they're adjacent angles on a straight line.
so therefore we get
51 + 66 + x + 180 - 132 + 78 + 180 - 139 = 360 (sum of exterior angle of polygon)
284 + x = 360
x = 76°
so it's C.
