Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have:
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have:
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have:
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points and
is given by,
Slope =
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope =
= (-1)
Therefore, slope of the line is (-1).
