Answer:
x = 25 degree
y = 155 degree
Step-by-step explanation:
angle cbd = 65 degree
angle cba + angle cbd = 180 degree .....................( angles in a linear pair )
angle cba + 65 degree = 180
angle cba = 180 - 65
angle cba = 115 degree
therefore , angle x = 105 degree
In triangle ABC ,
angle a + angle b + angle c = 180 degree ( property of a triangle )
30 + x + 115 = 180
x + 155 = 180
x = 180 - 155
therefore , x = 25 degree
y = 155 degree
