Answer:
b could be -1 or 0
Step-by-step explanation:
f(x) = 3x^2 +bx+2
if it has no real roots, the discriminant must be less than zero
b^2 -4ac <0
a=3 b=b c=2
b^2 - 4(3)(2) <0
b^2 - 24 <0
b^2 < 24
Taking the square root of each side
b< 2 sqrt(6) and b > 2 sqrt(6)
b could be -1 or 0
Your answer is the second statement, Angle D is an exterior angle because it is not inside the triangle. This is because exterior angles on any shape are angles that are not included in the shape, but are rather attached on the outside. I hope this helps!
radius and height are the correct choices
