Step 2.1

Factor $2$ out of $180$ .

$\frac{1}{2} \cdot \frac{2 (90)}{π}$

Step 2.2

Cancel the common factor.

$\frac{1}{2} \cdot \frac{2 \cdot 90}{π}$

Step 2.3

Rewrite the expression.

$\frac{90}{π}$

Step 3

$π$ is approximately equal to $3.14159265$ .

$\frac{90}{3.14159265}$

Step 4

Convert to a decimal.

$28.64788975 °$
