Answer:
B
Step-by-step explanation:
The top vertex of the triangle on the right = 40° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
y - 2 + 74 + 40 = 180 , that is
y + 112 = 180 ( subtract 112 from both sides )
y = 68 , so
y - 2 = 68 - 2 = 66
The 3 angles lying on the straight line sum to 180°
x - 1 + 40 + 66 = 180 , that is
x + 105 = 180 ( subtract 105 from both sides )
x = 75
