Answer:
[tex]-135\degree=-\frac{3}{4}\pi\: radians.[/tex]
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 [tex]\frac{\pi}{180\degree}[/tex].
That is [tex]-135\degree=-135\degree \times \frac{\pi}{180\degree}[/tex].
This can be simplified by canceling out the common factors to get,
[tex]-135\degree=-3\times45\degree \times \frac{\pi}{4\times 45\degree}[/tex].
This will give us,
[tex]-135\degree=-\frac{3}{4}\pi\: radians.[/tex]
