130 deg

$130 \deg$

Step 1

To convert degrees to radians, multiply by

\frac{π}{180 °}

$\frac{π}{180 °}$ , since a full circle is

360 °

$360 °$ or

2 π

$2 π$ radians.

130 ° \cdot \frac{π}{180 °}

$130 ° \cdot \frac{π}{180 °}$ radians

Step 2

Cancel the common factor of

10

$10$ .

Step 2.1

Factor

10

$10$ out of

130

$130$ .

10 (13) \cdot \frac{π}{180}

$10 (13) \cdot \frac{π}{180}$ radians

Step 2.2

Factor

10

$10$ out of

180

$180$ .

10 \cdot 13 \cdot \frac{π}{10 \cdot 18}

$10 \cdot 13 \cdot \frac{π}{10 \cdot 18}$ radians

Step 2.3

Cancel the common factor.

$10 \cdot 13 \cdot \frac{π}{10 \cdot 18}$ radians

Step 2.4

Rewrite the expression.

$13 \cdot \frac{π}{18}$ radians

$13 \cdot \frac{π}{18}$ radians

Step 3

Combine

$13$ and

$\frac{π}{18}$ .

$\frac{13 π}{18}$ radians
