Q. Which of the following radian measures is equal to 165∘?Choose 1 answer:(A) 125π radians(B) 127π radians(C) 65π radians(D) 1211π radians
Identify Formula: Identify the formula to convert degrees to radians. The formula is radians=degrees×(180°π).
Convert Degrees to Radians: Convert 165 degrees into radians using the formula. By substituting 165 degrees into the formula, we get 165∘×(π/180∘)=(165π/180) radians.
Simplify Fraction: Simplify the fraction(165π/180) to its lowest terms. Both the numerator and the denominator are divisible by 15. Dividing both by 15, we get (11π/12) radians.
Match to Choices: Match the simplified radian measure to the given choices. The correct match from the choices is (D)(1211π) radians.
