Show that you get the same prime factorization of 120 whether you begin with 120 = 2 × 60 or with 120 = 10 × 12.

2 -> 2

60 -> 5 x 3 x 2 x 2

120 -> 5 x 3 x 2 x 2 x 2

10 -> 2 x 5

12 -> 3 x 2 x 2

120 -> 5 x 3 x 2 x 2 x 2

Step-by-step explanation:

Good luck ;)

HI HOPE THIS HELPS oop caps

2 = 2

60  = 5 x 3 x 2 x 2

120  = 5 x 3 x 2 x 2 x 2

10  = 2 x 5

12  = 3 x 2 x 2

120  = 5 x 3 x 2 x 2 x 2

(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
