Question

in triangle ABC ,∠B= 30 ° , ∠B = 80° and ∠A = 70° , then prove that AB >BC > AC

Answer 1

Answer:

In any triangle side opposite to the largest angle is the longest side.

Here ZC is largest and side opposite to it is AB

..AB is the longest side.

Then comes ZA and side opposite to it is BC. ..BC is second longest.

Then comes ZB and side opposite to it is AC So it is the smallest side. So the decreasing order of sides is

AB > BC > AC

Hope you are clear
