construction of a quadrilateral ABCD in which BC=8cm, angle A=70°, angle B=160° and angle C=135°, AB=5cm is not possible because?
guys it's emergency and plz answer that person who knows the correct answer!!

Answer:
it is not possible because sum of all angle of quadrilateral is 360 digree but in question there are three angle whos sum is 360 where is 4 angle of tere are 4 angle then there sum will be grater than 360 digree
Answer :-
Its is not possible to construct as it violates angle sum property of a quadrilateral.
Verification :-
According to Angle sum property of a quadrilateral,
Sum of all interior angles = 360°
Now,in quadrilateral ABCD, it is given that :-
- ∠A = 70°
- ∠B = 160°
- ∠C = 135°
Now, According to Angle sum property of a quadrilateral,
∠A + ∠B + ∠C + ∠D = 360°
(Putting the values we get)
=> 70° + 160° + 135° + ∠D = 360°
=> 365° + ∠D = 360°
Now, if we try to find out ∠D, it will be in negative. We know that angles can't be in negative.
Therefore, the construction of quadrilateral with these dimensions is not possible.
=> Construction of Quadrilateral ABCD is not possible with those dimensions because it violates angle sum property of a quadrilateral.
