Answer:
answer is A and it feels wierd to answer this
Answer:
186.3
To find the answer you have to do inverse operations
9×20.7=186.3
186.3÷20.7=9
The exterior and an interior angles always add up to 180 degrees.
180-150=One exterior angle
180-150=30
We know that all of the exterior angles add up to 360
360/30= the number of sides
360/30=12
The shape has 12 sides.
I'm not 100% positive but I believe it would be the 14th person. 10+4=14. That's just my guess.
