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

Step-by-step 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

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
