Answer 1

Answer:

x = 90° and y = 60°

Step-by-step explanation:

angle ACB - angle ACD = 180°

y + 120° =180°

y = 180° - 120°

y = 60°

now , in ∆ABC

x + y + 30° = 180° (angle sum property)

x + 60° + 30° = 180°

x + 90° = 180°

x = 90°

Answer 2

x=90°;y=60°

Step-by-step explanation:

120+y=180(linear pair)

y=180-120=60°

30°+60°+x=180(angle sum property)

90°+x=180

x=180-90

=90°
