A, B and C. Show that OA + OB + OC>-
2
(AB + BC +CA)​

Answer 1

Step-by-step explanation:

power consumed by one device=250watt

power consumed by five devices=250×5 =1250 watt

time taken =10 hours

energy=power×time

energy consumed =1250×10

=12500J

Answer 2

Answer:

So I am considering that we have to prove. 2[OA+OB+OC] > AB+BC+CA. Given data: O is a point in the exterior of triangle ABC. To prove: 2 [OA +
