Question

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12

Answer 1

-π/12

Explanation:

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12

180 degrees = πrad

-15 degrees = x

Cross multiply

180x = -15π

x = -15π/180

x = -π/12

Hence the value of -15 degrees in radians is -π/12
