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:
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 +
