X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
C i thinks, but im not even sure so
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
False.
The Rational Root theorem states that P is a factor of the constant term and q is a factor of the leading coefficient.
