@Ellie_0790 The way I see it, is since the square root of a number can be a -ve number, we can have many possible solutions. Which each root being +ve or -ve.
The above answer are when the numerators are all combinations of possible roots.
A -ve denominator -ve adds solutions that are -ve.
@Beno10_MFC 105°. Assuming that the angle inside is 75° (180-60-45) . Based on internal angle being 75°, the external angle is 180° - 75° making it 105°.
@JayClarke27@Dr_Prodworthy@WilliamShatner By the M/D/Y logic, why don't you denote time by m/h/s?
For sorting, both h/m/s and s/m/h works.
But with the M/D/Y format, mathematical sorting is impossible.
My personal preference in denoting dates is YYYY-MM-DD. It's both elegant and non confusing.
