Given,

HK is the perpendicular bisector of GJ. So, <u>GK = KJ</u>.
GK = 2x + 10
KJ = 3x - 15

_______________

Find KJ .

_______________

First find the value of x

$\sf \: GK \: = KJ \\\sf 2x + 10 = 3x - 15 \\\sf 2x - 3x = - 15 - 10 \\ \sf - x = - 25 \\ \sf \: - > \boxed{\bf \: x = 25}$

Now, find the value of KJ.

$\sf3x - 15 \\ \sf= 3(25) - 15 \\ \sf=7 5 - 15 \\ = \boxed{\bf \: 60}$

-> The value of KJ is <u>6</u><u>0</u><u>.</u>

It's not actually 20 pts it's 10 pts if you send a question and you want 20 pts off it would be 10 for other ppl. like

10pts off = 5
20pts off = 10
30pts off = 15

and so on so it's like counting by 5's each time you lose points
