Find the distance of each of the following points from the origin:
B(– 5, 5)
Since it is given that the distance is to be found from origin so in this question we have to use the distance formula keeping one – point fix i.e. O (0,0), as shown below:
OB = √{(– 5 – 0)2 + (5 – 0)2}
= √{(– 5)2 + (5)2}
= √{25 + 25}
= √50
∴ OB = 5√2 units
