(B)

x = 180 - (100 + 25) [Sum of interior angles in triangle in 180°]
= 55°
y = 25° [Alternate angle]
m = x = 55° [Corresponding angles]
w = 180º - (55º + m) [Sum of interior angles in triangle in 180°]
= 180º - (55º + 55º) = 70º
w = z + 25º [Corresponding angles]
z = 70º - 25º  = 45°
x + y = 55º + 25º = 80°

w - y= 70º - 25º = 45°
