A picture frame is 112 inches wider than the picture it holds. Let f = width of the frame.
Let p = width of the picture.

answer is:

1.75 pounds

(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

x/3-10=8

x/3=18

x=48
