Answer:
THE ANSWER IS (3) 2√5 unit
EXPLANATION ::
Points P and Q trisect the line segment joining the points A( 0,8) and B(6,-4) such that P is near to A.
P divides line joining the points A( 0,8) and B(6,-4) in the ratio of 1 : 2
So co-ordinate of P is
= (1×6 + 2× 0 /1+2, 1×-4 +2×8 /1+2)
=(2, 4)
So
AP = √ ( 2 - 0) ² + ( 8 - 4) ²
= √2² + 4²
= 2√5 unit
