50 points! Can someone help me with the first one? I will mark brainliest.

I got 5 points Thanks a lot but pretty sure its perpendicular, i did a quick graph, their Nor parallel but could be perpendicular but not sure if 90 degrees. EDIT: its perpendicular I graphed it on a calc and I got 90 degrees

(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

536
