Question

How many radians is -135°?

Answer 1

- 3pi over 4

Explanation:

Answer 2

`-135\degree=-(3)/(4)\pi\: radians.`

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
`(\pi)/(180\degree)`.

That is
`-135\degree=-135\degree * (\pi)/(180\degree)`.

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

`-135\degree=-3*45\degree * (\pi)/(4* 45\degree)`.

This will give us,

`-135\degree=-(3)/(4)\pi\: radians.`
