I think it represents where something is starting from, like something growing up (a chart with rising numbers)
Your calculator says error because you cant have a square root of a negative number because there is no solution to that maybe recheck your equation and try again
1 equals 2. So 2 would be 50 as well.
50+50=100
And there's 360 degrees in total so you'd then subtract 360-100= 260
Then divide by 2 since the other 2 angles are the same
260/2=130
1=50
2=130
3=130
Hope this makes sense! :)
