Question

construct a triangle ABC, in which B=60°,C=90°and AB+BC+CA=12cm​

Answer 1

Here, ∠B = 60°, ∠C = 90°

and AB + BC + CA = 12 cm

We know that, sum of angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

Here, ∠B + ∠C = 60°+90°

= 150° >180° which is not true.

Thus, ΔABC with given conditions cannot be constructed
