At a pie eating contest johnny ate 8 pies in 5 minutes. how much time did he spend on each pie?

8:5 you divide 8 by 8 and 5 by 8 to see how long he spent on each pie:

which is 0.625 and  1: 0.625 which is 1 minute and 36 seconds

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
