Find one positive angle and one negative angle that are coterminal with the given angle. Explain.10. 255°12. -800°
Accepted Solution
A:
Answer: 10) 615° & -105° 12) -440° & 280°Step-by-step explanation:Coterminal means it is in the exact same spot on the Unit Circle but one or more rotations clockwise or counterclockwise.Since one rotation = 360°, add or subtract that from the given angle until you get a positive or negative number.10) 255° + 360° = 615° (this is a POSITIVE coterminal angle to 255°) 255° - 360° = -105° (this is a Negative coterminal angle to 255°)12) -800° + 360° = -440° (this is a Negative coterminal angle to -800°) -440° + 360° = -80° (this is a Negative coterminal angle to -800°) -80° + 360° = 280° (this is a POSITIVE coterminal angle to -800°)
