In triangle ABC, angle A = 40 degrees B angle = 50 degrees. Which side of the triangle is longest?

Let’s execute the solution, for this we will perform the following actions:
Angle C = 180 ° – angle A – angle B;
Let’s substitute:
Angle c = 180 ° – 40 ° – 50 ° = 90 ° – the largest angle in the triangle;
There is always a large side against a larger angle in a triangle,
means side AB has the greatest length.
