Answer:
A 144
B no
Step-by-step explanation:
Decagon is a 10 sided figure
interior angle = 180 (n-2)/n where n=10
180*(10-2)/10
180*8/10
144
To tessellate, the angle must divide evenly into 360
360/144= 2.5
This is not evenly so it will not tessellate
Let’s call the sum of the set of five numbers S and the sixth number N. We know the mean of the set of five numbers is 3k, so we can write the equation S/5 = 3k or S = 15k. When we add the sixth number the mean increases by k, so we can write the equations (S + N)/6 = 4k or S + N = 24k. Using S = 15k, we find that N = 9k. The ratio of the sixth number to the sum of the set of five numbers is therefore N/S = 9k/15k = 3/5.
Palarell lines has equal slop. so the slope of a line parallel to y = -x + 7 is equal to the slope of y = -x + 7 = -1.
