# If the distance of the point (x, 4) from the origin is 5 units, then the values of x are

A. ± 4

B. ±

C. ± 3

D. none of these

Answer :

Distance between two points =

Here the second point is the origin.

Squaring on both sides,

25 = x^{2} + 16

Or

x= + 3 or - 3

Let us show that the points (7, 9), (3, –7) and (–3, 3) are the vertices of a right angled triangle by calculation.

West Bengal MathematicsLet us prove that in both of the following cases, the three points are the vertices of an isosceles triangle:

(i) (1, 4), (4, 1) and (8, 8)

(ii) (–2, –2), (2, 2) and (4, –4)
