Answer:
a.b=[-1]
Step-by-step explanation:
This is a dot product of a and b
a.b =[6,-2,3].[2,5, -1] = [12-10-3] =[-1]
1. sum of exterior angles = 360
so one interior angles = 180 - (360/30) = 180 - 12 = 168 degrees
sum of all the interior angles = 168*30 = 5040
B
2. H
the sum of exterior angles of all polygons is 360 degrres
Answer:
0.96153846153
but it would make more sense in a lot of cases if it was 5.2/5
Step-by-step:
Answer:
x=66°
Step-by-step explanation:
48+x+x=180
2x=180-48
2x=132
x=132/2=66
