Answer 1

To find the measure of arc IJ given that m∠KIJ = 37 degrees, we can use the fact that an inscribed angle (like ∠KIJ) is half the measure of the arc it intercepts.

The inscribed angle ∠KIJ intercepts the arc IJ, so we can calculate the measure of arc IJ using the formula:

\[
m\!arc\ IJ = 2 \times m\angle KIJ
\]

Substituting the given value:

\[
m\!arc\ IJ = 2 \times 37 = 74 \text{ degrees}
\]

Therefore, the measure of arc IJ is **74 degrees**.

So the correct response is:

**74 degrees**.
