Question

How many radians is -135°?

Answer 1

Answer:

$-135\degree=-\frac{3}{4}\pi\: radians.$

Step-by-step explanation:

This question demands that we convert from a degree measure to a radian measure.

To convert from a degree measure to radians, multiply by $\frac{\pi}{180\degree}$.

That is $-135\degree=-135\degree \times \frac{\pi}{180\degree}$.

This can be simplified by canceling out the common factors to get,

$-135\degree=-3\times45\degree \times \frac{\pi}{4\times 45\degree}$.

This will give us,

$-135\degree=-\frac{3}{4}\pi\: radians.$
