Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
It should be B or C
Step-by-step explanation:
Answer: 0 slope
The y coordinat for both points is the same and there is no change in slope so it's a 0 slope
