What is the radian measure of 135°?

Question

Accepted Answer

1. Use the conversion rule: $1^\circ=\dfrac{\pi}{180}$ rad.
2. So $135^\circ=135	imes\dfrac{\pi}{180}=\dfrac{135\pi}{180}$.
3. Simplify by dividing numerator and denominator by 45: $\dfrac{135\pi}{180}=\dfrac{3\pi}{4}$.
4. Thus the radian measure is $\dfrac{3\pi}{4}$, so the correct choice is **(c)**.
