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

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
