Find the value of the variable. Round decimal answers to the nearest tenth. x =

15

Step-by-step explanation:

The hypotenuse of a triangle is a² + b² = c².

12² + 9² = c²

144 + 81 = 225

√225 = 15

(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
