HELP ASAP in the diagram below, DE is parallel to XY what is the value of y?

It is B- 80

Step-by-step explanation:

The two angles are same side interior angles which are supplementary (add up to 180). Therefore, 100+y= 180. 180-100=y. y=80

The answer would be 80 degrees

Step-by-step explanation:

This would be because if the DE and XY are parallel, then the corresponding angles would be equal. The answer would be 80 because the total degrees on a straight line is 180 and the bigger angle is 100 so the smaller would be 80

Hope that helped! Sorry about the previous answer

47

step-by-step explanation:

(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
