Find the value of y round to the nearest tenth! laws of sin !

43.5

Step-by-step explanation:

We first need to find 'x', then the missing angle to solve for y.

We start with..

(Sin 42)/31 = (Sin X)/37

   solving for X

      37(Sin 42)/31 = Sin X  (multiply both sides by 37 to isolate Sin X)

        0.798639756 = Sin X

          Sin^(-1) 0.798639756 = X

                         53° = X

Now we can find the missing angle needed to solve for y

42° + 53° + Y = 180°

     So Y = 85°

Solving for y gives us...

(Sin 42)/31 = (Sin 85)/y

           y(Sin 42) = 31(Sin 85)      (cross multiply)

           y = 31(Sin 85)/(Sin 42)    (divide both sides by Sin 42 to isolate y)

             y = 46.2     (rounded to the nearest tenth

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
