A fully shaded model represents 100%. Which model is shaded to represent 4/5 ?

- 70

this is the answer for you hope it

(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

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
