The segment JL has a definite length of [Drop Down 1]. Segments JK and KL have both definite lengths of [Drop Down 2] and [Drop Down 3], respectively. Both segments are [Drop Down 4]. JL=5x-9, JK=3x and KL=1x+4

Step-by-step explanation:

Your question is not well presented/formatted; however, I can deduce that the question requires that you calculate the following lengths;

JK, KL and JL

Given that

The relationship between the given parameters is:

Substitute 5x - 9 for JL; 3x for JK and 1x + 4 for KL

Now that the value of x has been solved, we can easily get the numeric values of JK, KL and JL by substituting 13 for x

So;

Hence;

Not sure but maybe:

X= 55

Y=70

Z=55
