Answer:
x = 47° and y = 23.5°
Step-by-step explanation:
1. AB is equal to AC therefore angle b is equal to angle C which is x.
2. By angle sum property angle A + angle B + angle C is equal to to 180 degree here we will find out angle x.
3. Also also given that AC is equal to CD therefore angle C A Dand angle C D A are equal.
4. angle x + angle ACD is equal to 180 degree here angle a CD is equal to 133 degree.
5.By angle sum property angle seed 80 + angle ACD + angle ADC is equal to 180 degree and we will find out angle y is equal to 23.5 degree
