Question

construct triangle abc ,in which bc=5.2cm,acb=45 degree and perimeter of triangleabc is 12cm ??????​

Answer 1

Perimeter of △ABC=10cm

⇒AB+BC+AC=10cm

⇒AB+5.2+AC=10cm

⇒AB+AC=4.8cm

A triangle can be only possible if the sum of the sides of a triangle is greater than the third side.

But here, AB+AC<BC

Hence, the construction of ΔABC is not possible.
