In euclidean geometry, the sum of the measures of the interior angles of a pentagon is 540°. predict how the sum of the measures of the interior angles of a pentagon would be different in spherical geometry.

a.
the sum would be greater than 540°.
b.
the sum would still be 540°.
c.
the sum would be less than 540°.
d.
the sum would less than or greater than, but never equal to, 540°.
