The anser is 20 that what i think
Answer:
-11
Step-by-step explanation:
-17+18-12=x
1-12=x=-11
-5i can be written as 0 + (-5)i
It is in the form a+bi where a = 0 and b =-5
So the point (a,b) is (0,-5)
The distance from the origin to this point is 5 units, therefore r = 5. This is the magnitude.
The angle is 270 degrees as shown in the attached image. You start on the positive x axis and rotate until you reach the point (0,-5)
This is why the
answer is choice A) 5(cos(270) + i*sin(270))
If the sum of any 2 sides is equal to or less than the third side it is Not a triangle.
So A :- we have 2+4 = 6 so its not a triangle.
also D is not a triangle because 8+3 < 12
what about B and C?
