Question

What is the radian measure of 150° ?

• A. 5∏/6
• B. 2∏/3
• C. 3∏/4
• D. ∏/3

Answer 1

Answer:

A. 5∏/6

To convert degrees into radians:

$\text{Radians} = \text{Degrees} \times \frac{\pi}{180}$

For $(150^\circ):$

$150 \times \frac{\pi}{180}$
$= \frac{5\pi}{6}$

So, the radian measure is:

$\boxed{\frac{5\pi}{6}}$
