Question

In a triangle
ABC, AB = 5cm, BC 6cm, CA= 7c
. If O is any point inside the triangle, then
OA + OB + OC is greater than​

Answer 1

Answer:

Step-by-step explanation:

In any triangle angle opposite to the longer side is larger.

Here CA is the longest side and angle opposite to it is ∠B.

So ∠B is largest angle.

Then comes BC and angle opposite to it is ∠A

So angle A is second largest.

Then comes AB angle opposite to it is ∠C

So ∠C is smallest.

So the decreasing order of angles is

∠B>∠A>∠C
