## anonymous one year ago what are the positive measures of the closest coterminal angle to 2.6 radians? Give exact answers (no decimals). Positive Angle : ______radians and Negative Angle:________ radians

1. anonymous

coterminal angles are in the same location on the circle. The closest coterminal angles will be one revolution away, so add and subtract $$2\pi$$

2. anonymous

I tried doing that but I got the wrong answers

3. anonymous

did you enter an exact number or a decimal?

4. anonymous

I subtracted 2pi from 13pi/5

5. anonymous

but your angle is 2.6, not 13pi/5. $$2.6 ± 2\pi$$ are the closest angles

6. anonymous

so the answer would be 2pi and -2pi?

7. anonymous

2.6 + 2π and 2.6 - 2π

8. anonymous

but you would have to convert the 2.6 into radians?

9. anonymous

you don't have to convert it. 2.6 is already in radians. You don't need to include a π there because not all angles are multiples of π.

make sense?
