Answer:
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Step-by-step explanation:
Each interior angle of a regular polygon is 4 times each exterior angle
∴sum of interior angles: (n-2)*180=4*360
n-2=8
n=10
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Answer: 170
Steps:
Range- the difference between the greatest and smallest value of a data set.
546 - 376 = 170
Answer:
18 divided by 4.
Step-by-step explanation:
1/2x9= 4 1/2 and when you divide 18 divided by 4 you get 4 1/2 (4.5)
Answer:
139
Step-by-step explanation:
supplementary angles add up to equal 180
so to find the measure of angle ABC we subtract the given angle from 180
180-41=139
so we can conclude that angle ABC= 139
