2x_2.20_40

y+60+40_180

y_180-100

y_80

you will happy of this question so plzz thanks

Answer 2

Answer: x=20° and y=80°

Step-by-step explanation:

Since it is a ║gm, ∠B=∠D ⇒ 4x = y

In triangle ACD,

∠A + ∠C + ∠D = 180°    (Angle Sum Property)

⇒2x + 3x + y = 180°

⇒2x + 3x + 4x = 180°

⇒9x = 180°

⇒x = 180° ÷ 9 = 20°

Now, ∠D= y = 4x = 4 × 20° = 80°
