MCQ
Assertion (A): Distance between (5, 12) and origin is 13 units.
Reason (R): D = $\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}$
  • ✓
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • D
    A is false but R is true.
✓

Answer

Correct option: A.
Both A and R are true and R is the correct explanation of A.
(A) Both A and R are true and R is the correct explanation of A.
Explanation:Distance of point (5, 12) from 8 origin is given, d = $\sqrt{(5-0)^2+(12-0)^2}$
$=\sqrt{25+144}=\sqrt{169}=13$
