Question

what is the correct measure of ∠doe? the outer scale was used instead of the inner scale. the inner scale was used instead of the outer scale. m∠doe should be calculated as the absolute value of the sum of the measures that od and oe pass through. m∠doe should be calculated as the absolute value of the difference of the measures that od and oe pass through.

Explanation:

To find the correct measure of \(\angle DOE\), we analyze the protractor scales. When using a protractor, if two rays (OD and OE) are measured, the angle between them is the absolute value of the difference of their measures (since they are on the same side relative to the baseline, like OA or OB). The sum would be incorrect, and scale mix - up is not the case here. So the correct way is to calculate it as the absolute value of the difference of the measures that OD and OE pass through.

Answer:

\(m\angle DOE\) should be calculated as the absolute value of the difference of the measures that \(OD\) and \(OE\) pass through.
