Answer:
11 units
Step-by-step explanation:
It's clear that,
JL = JK + KL
Given that,
JK ⇒ ( x + 8 )
KL ⇒ 10
JL ⇒ 7x
So, by using these data we can make an expression like this.
JL = JK + KL
7x = x + 8 + 10
Now make x the subject and find the value of x.
7x = x + 8 + 10
7x = x + 18
7x - x = 18
6x = 18
6x/6 = 18/6
x = 3
And now let us find the value of JK.
JK ⇒ x + 8
To, find the value of JK we have to replace with 3.
JK ⇒ x + 8
JK ⇒ 3 + 8
JK ⇒ 11 units
