Question

Find the values of x and y and then show that AB || CD...plz give the answer step by step...​

Answer 1

Answer:

50 + x = 180°        (LINEAR PAIR)

x = 180 - 50

  = 130°

Since there is a pair of corresponding angles, AB II CD

y = 130°   (VERTICALLY OPP. ANGLES ARE EQUAL)

                                         OR

x = y      (ALTERNATE INTERIOR ANGLES ARE EQUAL)

y = 130°    (VERTICALLY OPP. ANGLES ARE EQUAL)

Since x = y, then x = 130°

Since there is a pair of alternate interior angles present, AB II CD

HOPE THIS HELPS... :)
