Find the discriminant and the number of real roots for this equation. x^2 + 2x + 8 = 0 A. -28; no real roots B. 32; one real root C. 32; two real roots D.-28; one real roof​

Step-by-step explanation:

A is correct option there are no real roots

because discriminant is less than zero

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
