Answer:
66
Step-by-step explanation:
the sum of all exteriors should be 360. so add all of them up and you get 294. then you subtract it from 360 and you are left with the only missing exterior angle, 66.

Answer:
- boat: 48 km/h
- current: 14 km/h
Step-by-step explanation:
The upstream speed is ...
u = (204 km)/(6 h) = 34 km/h
The downstream speed is ...
d = (372 km)/(6 h) = 62 km/h
The speed of the boat in still water is the average of these values:
b = (34 kph +62 kph)/2 = 48 kph
The speed of the water is the difference between the boat's speed and the speed made good:
w = 48 -34 = 14 . . . km/h
The rate of the boat in still water is 48 km/h. The rate of the current is 14 km/h.
The range of the dataset = 47
What is the range of a dataset?
The range of a set of data is the difference between the greatest number and least number
The given data set is:
{14, 25, 61, 18, 30, 32, 28, 45, 21}
The greatest number = 61
The least number = 14
The range of the dataset = Greatest Number - Least Number
The range of the dataset = 61 - 14
The range of the dataset = 47
