Answer:
0 to StartFraction pi Over 2
Step-by-step 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 [tex](0,90^o)[/tex]
Convert to radians
Remember that
[tex]\frac{\pi}{2}\ radians=90^o[/tex]
therefore
the range in radians is [tex](0,\frac{\pi}{2})[/tex]
