Answer 1

Answer:

Let the point where BC meets AD be O

Step-by-step explanation:

x = 90° (Because AD is perpendicular to BC)

Using angle sum property

y +x+30° = 180°

=> y = 180° - 90° - 30° = 60°

z= y ( the two triangles AOC and DOB are congruent)

Answer 2

X=90 vertically opposite angle
Y= 90+30+y=180
Y= 60

Z = 60 alternate interior angle
