Supplementary angles - Sum = 180°
X + Y = 180°
x = larger angle
y = smaller angle
x = 2y - 60
x + y = 180
x = 180 - y
2y - 60 = 180 - y
2y - 60 -180 + y
3y = 240
y = 80°
x+y = 180
x+80° = 180°
x = 100°
Really, no. But mathematically,
you can do the job with
+√177
and
- √177 .
2x²+x-6=0
(2x-3)(x+2)=0
x=3/2 or -2
