Angles in a triangle add up to 180
2:3:4...added = 9
2/9 (180) = 360/9 = 40 <=== smallest angle
3/9 (180) = 540/9 = 60
4/9 (180) = 720/9 = 80
The only correct answer is C.) 9
✓16 = 4
5+4= 9
x = 9

So, we want

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
