is the value of y - x?
D
С

owy
40°
A
B​

Answer 1

Answer:

y-x = 40

Step-by-step explanation:

IN ΔAOB -:

∠A+∠B = ∠COB   [Exterior angle property]

∠A = 40

∠B = x   [Alternate interior angle]

40 + x = y

y-x = 40

Answer 2

Answer:

Y = 90°(diagonal of rhombus intersect at 90° always)

X=50° (90°+40°(alt angle) +x=180°)

hence y-x = 90-50= 40°
