Question

The distance from the origin to the point (-20, 21) is

Answer 1

For this case we have that by definition the distance between two points is given by:

`d = \sqrt {(x2-x1) ^ 2 + (y2-y1) ^ 2}`

Where we have the points are given by:

`(x2, y 2) = (- 20, 21)\\(x1, y 1) = (0, 0)`

Substituting values we have:

`d = \sqrt {(- 20-0) ^ 2 + (21-0) ^ 2}\\d = \sqrt {(- 20) ^ 2 + (21) ^ 2}\\d = \sqrt {400 + 441}\\d = \sqrt {841}\\d = 29`

Answer:

The distance from the origin to the point (-20, 21) is:

d = 29
