Options:
(A) 120°
(B) 150°
(C) 135°
(D) 160°
Show Answer
Answer: B
Explanation:
(A) Incorrect. 120° is equivalent to $\frac{2\pi}{3}$ radians.
(B) Correct. To convert radians to degrees, we use the formula: degrees = radians × (180°/π). For $\frac{5\pi}{6}$, we get $\frac{5\pi}{6}$ × (180°/π) = 150°.
(C) Incorrect. 135° is equivalent to $\frac{3\pi}{4}$ radians.
(D) Incorrect. 160° is not equivalent to $\frac{5\pi}{6}$ radians.
