Answer:
The angle 1 will be equal to 55°.
Step-by-step explanation:
See the attached diagram.
Here, line m and line n are parallel and line k is the transverse line.
So, from the properties of parallel lines with a transverse line the angle 55° and the angle 1 are corresponding angles and they are equal.
Therefore, angle 1 will be equal to 55°. (Answer)

Answer:
A quadratic equation can be written as:
a*x^2 + b*x + c = 0.
where a, b and c are real numbers.
The solutions of this equation can be found by the equation:
Where the determinant is D = b^2 - 4*a*c.
Now, if D>0
we have the square root of a positive number, which will be equal to a real number.
√D = R
then the solutions are:
Where each sign of R is a different solution for the equation.
If D< 0, we have the square root of a negative number, then we have a complex component:
√D = i*R
We have two complex solutions.
If D = 0
√0 = 0
then:
We have only one real solution (or two equal solutions, depending on how you see it)
