Question

Find the value of 'c' if the distance between the point (c, 4) and the origin is 5 units?

• A. 3
• B. -3
• C. Both A and B
• D. None of these

Answer 1

The correct option is C

Both A and B

The distance between the point (c, 4) and the origin is 5 units

Using Pythogoras theorem,
$\sqrt{c^2+4^2}=25c^2=25-16c^2=9C=3,-3$
