Answer 1

Answer:

Measure of segment JL is 20 cm.

Step-by-step explanation:

By applying geometric mean theorem in the given right triangle,

$\frac{JM}{KM}=\frac{KM}{ML}$

$(KM)^2=(LM)(ML)$

$8^2=(JM)(4)$

$JM=\frac{64}{4}$

$JM=16$

Since, $JL=JM+ML$ [By segment addition postulate]

$JL=16+4$

$JL=20$ cm

Therefore, measure of segment JL is 20 cm.
