The figure on the left represents a scale drawing 5yd. of the figure on the right 2 in. what is the scale?

90 : 1

Step-by-step explanation:

1 yard = 36 inches

5 yards = 36×5 = 180 inches

180 : 2

90 : 1

(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
