Find all missing angles

2=72

57=3

2+3+4=180

71+57+x=180

129+x=180

x=180-129

x=51

57+90+Y=180

147+y=180

y= 33

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
