Answer:
Step-by-step explanation:
For example, we'll use this quadratic equation.
To understand how to plug it into the formula we need to know what each term represents.
So the equation above would be put into the formula like this.
Then we would solve
Now, the equation will branch off into one that solves when addition and one when subtraction.
So x={-3, -2} (-3 and -2)

Answer:
m<1= 120
Step-by-step explanation:
1. we know supplementary angles equals 180. the angle 130 is part of a supplementary angle so we can subtract it by 180 to see that missing angle.
2. we also know that all triangles three angles add up to 180. So if we add the number we know 70+50 (50 is from subtracting 130 from 180), Once we find that answer, we subtract it from 180 to find angle 2 which is 60 degrees
3. Last step, angle 2 is part os a supplementary angle in which the two angles add up to 180. So, subtracting 60 from 180 will get you the degree of the angel one which his 120 degrees.
