Answer: Since it's a circle, we know that the sum of the measures of the arcs is 360°. We're given two arcs: 46° and 87°. Let's add them up:
46° + 87° = 133°
To find the measure of the missing arc, we can subtract the sum of the given arcs from 360°:
360° - 133° = 227°
So, the measure of the missing arc is 227°.
