Question

To construct a triangle ABC in which AB = 6.2 cm and ∠A = 70° is not possible when sum of BC and AC is equal to ?

Answer 1

Answer:

(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.
