BARSIC [14]
40 is greater because we can easily see that 1/4 is not a whole number that is less than 40 and the 40/14 will be changed into a lesser mixed number which again, is less than 40.

Help for final I’d appreciate it!
mihalych1998 [28]

Answer:

y=76 degree(being vertically opposite angle)

y+x=180 degree(being linear pair)

76+x=180

x=180-76

x=104 degree

x=z(being vertically opposite angle)

104=z

therefore z=104 ,y=76,x=104
