x + 57 = 107
x = 107 - 57
x = 50
40 + 107 + x =180 (angle sum property)
x = 180-40-107
x = 33
65+33+y=180
98+y=180
y=180-98
y=82

Figure a => ∠bac = 180 - 107 = 73
∠abc = 180 - 73 - 57 = 50 .!!
Hence ∠abc = 50 degree
Figure b => ∠acd = 180 - 107 - 40 = 33
∠ acb = ∠acd + ∠dcb
= 33 + 65
= 98
∠bce = 180 - ∠acb
= 180 - 98
= 82 degree .
Hence x = 33 degree and y = 82 degree..!
