In a plane, there are 37 straight lines, out of which 13 pass through the point A and 11 pass through the point B. Besides, no three lines pass through the same point, no line passes through both points A and B, and no two lines are parallel. The number of intersection points the lines have is equal to

If z₁and z₂ are any two complex numbers, then

|z₁ + z₂| |z₁| + |z₂|

|z₁ + z₂| > |z₁| + |z₂|

|z₁ + z₂| |z₁| + |z₂|

|z₁ + z₂| = |z₁| + |z₂|
