Question
Find distance of point A(6, 8) from origin.
Advertisements
Solution
Let A(x1, y1) = A(6, 8), O(x2, y2) = O(0, 0)
∴ x1 = 6, y1 = 8, x2 = 0, y2 = 0
By distance formula,
d(A, O) = `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2`
= `sqrt((0 - 6)^2 + (0 - 8)^2`
= `sqrt(36 + 64)`
= `sqrt(100)`
= 10
∴ The distance of point A(6, 8) from origin is 10 units.
