Question

Find the reference angle for the given angle: 780 degrees

Answer 1

The reference angle of an angle is obtained by subtracting the angle with 360n where n is an integer until the resulting angle is below 360. In this case, 780 - 360 is equal to 420. this is still more than 360, hence 420 - 360 is equal to 60. the answer thus is 60 degrees.
