Question

The construction of a AABC in which AB = 6 cm, ZA= 45° is possible when (BC + AC) is​

Answer 1

Step-by-step explanation:

(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.
