Find the measure of a positive angle coterminal with – 29​𝜋 20 radians. Give the answer in simplest form.

Answer 1

-29 ∏/20 or -29∏ 20

which one is correct ?

Answer 2

2π radians is 360 degrees, so we can add 2π radians to any angle and the result will be "coterminal" with the original angle.

2π radians = 40π/20 radians, so let's add 40π/20 radians to our original angle of -29π/20 radians:

-29π/20 radians + 40π/20 radians = 11π/20 radians.

11π/20 radians is positive and is in simplest form.
