If a quadratic equation with real coefficients has a discriminant of –36, then what type of roots does it have? 2 real, rational roots

2 real, irrational roots

1 real, rational root

2 imaginary roots

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
