Answer:
D
Step-by-step explanation:
1+2+2+3+3+3+4+5+6+6+7+7+7+8+9=73
73/15≈5
The square root of 81 is 9
16.5 because it would 165 divided by 10, so if you were to round it’s 17 because you can’t really get half a person.

b is the angle being measured while a is the angle at a point with b
Step-by-step explanation:
The only time we use 360 for calculating an angle is when the two angles are at a point as both of them assuming a and b sum up to 360°.
Therefore a + b = 360
and if b is being measured, b = 360 -a
