Question

4. If AB II CD, find x and y​

Answer 1

Answer:

x=70°, y=70°

Step-by-step explanation:

ABC=DCE=40°(AB||CD)(Corresponding angles)

ACB+ACD+DCE=180°(Linear pair)

y+70°+40°=180°

y+110°=180°

y=180°-110°

y=70°

BAC+ABC+ACB=180°(Angle sum property of a triangle)

x+40°+y=180°

x+40°+70°=180°

x+110°=180°

x=180°-110°

x=70°
