A light flashes every 3 minutes, a second light every 90 seconds, and a third light every 45
seconds. If the three lights flash together at 8:00 AM Monday morning, when is the next time
they will all flash together?

(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

the answer is mp
