Answer 1

oh and please show me how u do it ? thanks a bunch guys

Answer 2

It's an isosceles triangle, we are given AB=AC.
We know that angles opposite to equal sides are equal so
angle B= angle C
angle C=55 (given)
angle B or y=55
Now in a triangle the sum of all the angles is 180
so
z+y+55=180
z+55+55=180
z=180-110=70
AD || BC
x=55 ( alternate interior angles are equal)
