Answer:

1) x=30 degrees

2)y=20 degrees

1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)

2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

(I hope this makes sense)

Any one know how to find the roots of an equation?
soldier1979 [14.2K]
So what you do is
make into ax^2+bx+c=0 form

add-9/2 to both sides
y^2-2y+9/2=0
now we use the quadratice formula which is
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

ax^2+bx+c=0
1y^2-2y+9/2
a=1
b=-2
c=9/2
subsitute
x=\frac{-(-2)+/- \sqrt{(-2)^{2}-4(1)(9/2)} }{2(1)}
x=\frac{2+/- \sqrt{4-(36/2)} }{2}
x=\frac{2+/- \sqrt{4-(18)} }{2}
x=\frac{2+/- \sqrt{-14} }{2}
x=\frac{2+/- \sqrt{-14} }{2}
x=1+/- \frac{\sqrt{-14} }{2}
x=1+/- \frac{\sqrt{14} \sqrt{-1}}{2}
x=1+/- \frac{\sqrt{14} i }{2}
x=1+/- \frac{ i \sqrt{14} }{2}

answer is C
