$- 10 °$

Step 1

To convert degrees to radians, multiply by $\frac{π}{180 °}$ , since a full circle is $360 °$ or $2 π$ radians.

$- 10 ° \cdot \frac{π}{180 °}$ radians

Step 2

Cancel the common factor of $10$ .

Step 2.1

Factor $10$ out of $- 10$ .

$10 (- 1) \cdot \frac{π}{180}$ radians

Step 2.2

Factor $10$ out of $180$ .

$10 \cdot - 1 \cdot \frac{π}{10 \cdot 18}$ radians

Step 2.3

Cancel the common factor.

$10 \cdot - 1 \cdot \frac{π}{10 \cdot 18}$ radians

Step 2.4

Rewrite the expression.

$- 1 \cdot \frac{π}{18}$ radians

Step 3

Rewrite $- 1 \frac{π}{18}$ as $- \frac{π}{18}$ .

$- \frac{π}{18}$ radians
