Question

ABCD is a parallelogram in which ∠DAB =60 and ∠DBC = 70


. Find x and y from the


figure.

Answer 1

Answer:

x = 50° , y = 70°

Step-by-step explanation:

y = 70°      (DA║CB, Alternate interior angle)

∠DCB = 60°     (Opp. angles are equal)

In Δ DCB,

x + 70° + ∠DCB = 180°

x + 70° + 60° = 180°

x + 130° = 180°

x = 180° - 130°

  = 50°
