How many times greater is the value of the 9 in 39,865 than the value of the 9 in 67,492

(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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
