What is mc004-1.jpg radians converted to degrees? if necessary, round your answer to the nearest degree. 30° 45° 60° 90°

From my research, the radian is equal to pi/3. To convert from radians to degree, we multiply the given radian by (180/pi). This is shown below:

(pi / 3)*(180 / pi) = 60 degrees.

Therefore, the equivalent of pi/3 radians is 60 degrees. Among the choices, the correct answer is the third one.

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
