Answer:
0.9212 (Answer b)
Step-by-step explanation:
Note that sin 52 deg 47 min = sin (52 47/60 deg)
Using the fact that pi radians = 180 degrees, convert the argument of the sine function to radians:
sin ( [52 47/60][pi rad][180 deg] )
= sin ( 0.2932 pi) = 0.9212
Using a calculator to evaluate this, we get 0.2891
