Time zone of Singapore is =8. Time zone of Sri Lanka (approx) +5 1/2. If an air craft leaves Singapore at 1900h, what is the time in Sri Lanka at the moment ?

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

(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
