Step-by-step explanation:
To find the roots of the equation, factor the equation and set each factor equal to 0 or use the quadratic equations. The quadratic expression does not factor and must be solved using the quadratic formula.
where a = 1, b=-3, and c=1
Answer:
The angle has a measure of radians.
Step-by-step explanation:
According to the statement, an angle centered at the center of the circle covers an arc of units, the arc is a portion of the circunference. We include a figure representing the circle below.
Where:
- Radius, measured in units.
- Arc, measured in units.
- Angle of the arc, measured in radians.
From Geometry, we can calculate the length of the arc by means of this equation:
(1)
If we know that and , then the angle of the arc is:
The angle has a measure of radians.
