What is the degree form for 4π5 radians?
°____
What is a positive coterminal angle to −32° that is between 500° and 1000° and a negative coterminal angle to −32° that is between −500° and −50°?
positive coterminal angle: °____
negative coterminal angle: °___
In which quadrant does the terminal side of the angle 257° lie?
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
I really appreciate your help. Thanks so much!
+128407 4pi/5 * (180) / pi = (4/5)(180) = 144°
posive coterminal angle = 2*360 - 32 = 688°
negative coterminal angle = -360 - 32 = -392°
[ if the negative coterminal angle is supposed to be between - 500 and -1000, we have
-2*360 - 32 = -752° ]
257° lies between 180° and 270°....so......Quadrant III
