She need 3 bags since the area of the triangle is base x height /2
Area 20*6=120
120/2=60
60/20= 3 since each bag covers 20m^2
The answer is C, Region A.
Answer:
B
Step-by-step explanation:
Using the exact values
cos150° = - cos30° = - 
sin150° = sin30° = 
Given
z = 4(cos150° + isin150° ) , substitute values
= 4(- + i )
= - 2
+ 2i , that is
(- 2, 2 ) → B
You take the difference so 1200-1068=132 and then you take the original divided by the difference so 1200/132 so it would be 9.09%
