Answer:

0 to StartFraction pi Over 2

Explanation:

we know that

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

so

The central angle in degrees is within the range
(0,90^o)

Convert to radians

Remember that


(\pi)/(2)\ radians=90^o

therefore

the range in radians is
(0,(\pi)/(2))

0 to StartFraction pi Over 2
