One street light flashed every 4 seconds another street light flashes every 6 seconds if they both just flashed as the same movement how many seconds will it take before thwart flash at the same time again

Time for light A's Flash = 4 seconds

Time for light B's Flash = 6 seconds

Duration between the lights = 6-4=2

Duration to flash again = LCM of 6, 4

2/6,4

2/3,2

3/3,1

/1,1

2x2 x 3

4 x 3

= 12 seconds

step-by-step explanation:

3024 rhe base is what up in worry about

(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
