$- \frac{π}{2}$

Step 1

To convert radians to degrees, multiply by

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

$360 °$ or

$2 π$ radians.

$(- \frac{π}{2}) \cdot \frac{180 °}{π}$

Step 2

Cancel the common factor of

$π$ .

Step 2.1

Move the leading negative in

$- \frac{π}{2}$ into the numerator.

$\frac{- π}{2} \cdot \frac{180}{π}$

Step 2.2

Factor

$π$ out of

$- π$ .

$\frac{π \cdot - 1}{2} \cdot \frac{180}{π}$

Step 2.3

Cancel the common factor.

$\frac{π \cdot - 1}{2} \cdot \frac{180}{π}$

Step 2.4

Rewrite the expression.

$\frac{- 1}{2} \cdot 180$

$\frac{- 1}{2} \cdot 180$

Step 3

Cancel the common factor of

$2$ .

Step 3.1

Factor

$2$ out of

$180$ .

$\frac{- 1}{2} \cdot (2 (90))$

Step 3.2

Cancel the common factor.

$\frac{- 1}{2} \cdot (2 \cdot 90)$

Step 3.3

Rewrite the expression.

$- 1 \cdot 90$

$- 1 \cdot 90$

Step 4

Multiply

$- 1$ by

$90$ .

$- 90$

Step 5

Convert to a decimal.

$- 90 °$
