you have to do 6+12 which equals 18

x=18

so it will be 18-6=12

your welcome :)

x = 18

Step-by-step explanation:

So just substitute the value of y in the equation.

x - y = 12

x - 6 = 12

Then solve for x:

x - 6 = 12

  +6    + 6

x = 18

So the solution would be x = 18.

(If you want it in a coordinate then (18, 6) )

(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
