Is 9/2 and 4 1/2 equivalent

Yes, they are equivalent

Step-by-step explanation:

Equivalent fractions are equal in value to each other. The only difference is that 9/2 is an improper fraction while 4 1/2 is a mixed number. In decimal, they both equate to 4.5

(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
