To express an angle in degree from radian we multiply it with (180/pi)

a. 11pi/6 

in degrees --> (11pi/6) * (180/pi)

 = 11*30 degrees

= 330 degrees

b. 34pi / 15

in degrees --> (34pi/15) * (180/pi)

 = 34*180 / 15 degrees

= 34*12 degrees

= 408 degrees 

If we scale 408 degrees into 0-360 degrees scale, then

408 degrees = 408-360 = 48 degrees
