My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.

Answer:
(n+2)(n+1)
Step-by-step explanation:
Write out the numerator and cancel common factors:
(n+2)!/n! = (n+2)(n+1)n!/n! = (n+2)(n+1)
_____
You might be expected to multiply it out:
= n·n +2·n +n·1 +2·1
= n² +3n +2
