The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.
Ans: We can use Angle sum property:
A + B + C + D = 360
A + 3x + 2x + 5x = 360
A + 10x = 360
A = 360/10x= 36x
A = 36x
The equivalent of 4 meters is 4.374 yards
