Find the distance of each of the following points from the origin:
A(5, – 12)
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:
OA = √{(5 – 0)2 + (– 12 – 0)2}
= √{(5)2 + (– 12)2}
= √{25 + 144}
= √169
∴ OA = 13 units
