ANSWER.
=> h, k = √65
EXPLANATION.
=> h, k is the perpendicular distance from
( 1,2,3 ) to the x-axis , x-axis
To find hk = ?
As we know that,
perpendicular distance from the point
( 1,2,3 ) from the x-axis.
=> y, z are perpendicular from x-axis.
=> h = √(y)² + (z) ²
=> h = √(2)² + (3)²
=> h = √4 + 9
=> h = √13
perpendicular distance from the point
( 1,2,3) from z-axis.
=> x, y are the perpendicular from z-axis.
=> k = √(x)² + (y)²
=> k = √(1)² + (2)²
=> k = √5
Therefore,
value of hk = √13 X √5 = √65
Hence option [D] is correct.
