Answer:
B
Explanation:
(x - 1) and 74° are corresponding angles and are congruent , so
x - 1 = 74 ( add 1 to both sides )
x = 75
the top angle of the triangle are alternate angles and are congruent
top angle = 40°
the sum of the 3 angles in a triangle is 180°
sum the 3 angles and equate to 180
y - 2 + 40 + 74 = 180
y + 112 = 180 ( subtract 112 from both sides )
y = 68
