Answer:
(Segment JL)(Segment ML)=10(6.4)=64 units
Step-by-step explanation:
In the given information, triangle JKL with right angle at K. Segment JK is 6 and segment KL is 8. Point M is on segment JL and angles KMJ and KML are right angles.
we have to choose the correct option.
In order to choose we have to find the segment ML
Let ML=x therefore JM=10-m
In triangle JMK, by Pythagoras theorem

In triangle KML

From above two equations we get

⇒ 
⇒ 
⇒ m=6.4 units
(Segment JL)(Segment ML)=10(6.4)=64 units
Hence, last option is correct
