Answer 1

Answer:

As per the given condition,

AB=CD that means Angle ACB = Angle DAC = 20°

Now if we look in ∆ABC,

Angle A+ Angle B + Angle C= 180°(Angle sum property of a triangle)

Angle A+ 80°+20°=180°

Angle A= 180°-100°=80°

Now,

Angle BAC= Angle BAD+ Angle DAC

80°=Angle BAD+20°

Angle BAD=80°-20°=60°

Now,in ∆ABD

Angle A+ Angle B + Angle D= 180°

60°+80°+Angle D= 180°

Angle D= 180°-140°=40°

Hence x=40°
