Q18 of 40 Page 3

The distance between the origin and a point (x, 4) is 5 units. Find the value of x.

Concept Used:


Distance of point (0, 0) from a point (x, y)


Explanation:


The distance between (x, 4) and origin



x2 + 16 = 25


x2 = 25 – 16


x2 = 9


x = ±3


Hence, the values of x are +3 and -3.
