Answer: The answer is B.
Step-by-step explanation:
Angle ABC is a straight angle, which is 180 degrees, so you can rule out answers C and D.
For angle EBG, simply count the measures of the angle on the protractor. From the right, you start at 55. You end at 100. Subtract 55 from 100 to get a measure of 45 degrees.
Answer:
Discriminant is 60
Step-by-step explanation:
the discriminant of ![3x^2 + 6x = 2](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x%20%3D%202)
To find discriminant , first we write the equation in the form of
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
![3x^2 + 6x = 2](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x%20%3D%202)
Subtract 2 on both sides
![3x^2 + 6x-2=0](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x-2%3D0)
a=3, b=6, c=-2
Formula for discriminant is ![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
Plug in the values
![b^2-4ac=(6)^2-4(3)(-2)=60](https://tex.z-dn.net/?f=b%5E2-4ac%3D%286%29%5E2-4%283%29%28-2%29%3D60)
