Find the formula

the no. of collinear points and the no. of rays on common vertex are 1234 while the no. of segments and the no. of angles formed are 0136. QUESTION: what is the formula we use to get the no. of angles formed based on the no. of rays (n) given?

the no. of angles formed are 0136
Is that number supposed to be 136?

Where are these angles?

I think that this type of exercise either needs a diagram OR a considerably-detailed description.
