Answer 2

Answer:

angle ACB = 30°

angle DAC = 60°

angle BAC = x

angle ABC = y

angle DAC + angle BAC = 180°[Linear Pair]

60° + x = 180°

x = 180 - 60

x = 120°

angle BAC = 120°

angle BAC + angle ACB + angle ABC = 180°

120° + 30° + y = 180°

150° + y = 180°

y = 30°

OR

angle ACB = 30°

angle ACB = 30° angle DAC = 60°

angle ABC = y

angle DAC = angle ACB + angle ABC

[Exterior angle is equal to

sum of two opposite

interior angles]

60° = 30° + y

y = 60° - 30°

y = 30°

Thus y = 30°

Thus correct option is C
