▪︎The property that satisfies –14 + 6 = –8 (Integer) is: (a) The associative property
(b) the commutative property
(c) the closure property
(d) the distributive property​

commutative properties satisfies the property.

(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
