Question

Find an angle between 0° and 360° that is coterminal with 1260° . (b) find an angle between 0 and 2Ï that is coterminal with â3Ï10

Answer 1

to find coterminal angle you either add or subtract 360 degrees. in this case we can subtract

1260-360=900
900-360= 540
540-360= 180


you do the same process with the following questioin to get the answer of 230 degrees.
