Answer: The answer is (A). greater than.
Step-by-step explanation: We are to compare the measure of each angle of a regular octagon with the measure of each exterior angle of a regular hexagon.
We know that each interior angle of a regular octagon is
o = 135°.
And the measure of each exterior angle of a regular hexagon is given by

Since 135° > 60°, so the complete statement is
The measure of each angle of a regular octagon is <u>greater than</u> the measure of each exterior angle of a regular hexagon.
Thus, (A) is the correct option.
