(a) Given, BC = 6 cm and ∠B= 45°
We know that, the construction of a triangle is not possible, if sum of two sides is less than or equal to the third side of the triangle.
i.e., AB + BC < AC
⇒ BC < AC – AB
⇒ 6 < AC-AB
So, if AC – AB= 6.9 cm, then construction of ΔABC with given conditions is not possible.

HEY HERE IS YOUR ANSWER....
A) Given, BC = 6cm and <B = 45° We know that, The construction of a triangle is not possible, if sum of two sides is less than or equal to the third side of the triangle.
i.e., AB + BC < AC
BC < AC - AB
6 < AC - AB
So, if AC - AB = 6.9 cm, then construction of Angle ABC with given conditions is not possible.
