Which of the following is not an exact number? the number of seconds in a year the number of millimeters in a kilometer the number of liters in a gallon the number of centimeters in an inch the number of grams in a kilogram

b. x- 48 =120

step-by-step explanation:

(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'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
