Question

Is ∆ ABC possible if ∠A = 50 ° , ∠B = 130° and ∠C = 40° ? Justify.

Answer 1

angle a+b+c=180 degree
a+b+c=180
50+ 130 +40=180
220≠180

Answer 2

No,triangle ABC is not possible if angle A=50°,angle B=130° and angleC=40°.It is because the sum of all the angles of a triangle is 180°.But in this the sum of the angles is 220°.
