ANOTHER ONE TO TAKE A LOOK AT DOUBLE OR NOTHING

The answer is 3rd point

Step-by-step explanation:

By looking at the table :

10-10.99,

$15.95 (1 dot)

20-29.99,

$21.52, $25.55, $27.78, $29.90 (4 dots)

30-39.99,

$33.98, $36.77 (2 dots)

40-49.99,

$43.44 (1 dot)

50-59.99,

$51.25 (1 dot)

60-69.99,

$60.54, $64.56, $67.89 (3 dots)

Then you can determine number of dots in each range.

(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
