All you have to do is add up the side lengths we already know then subtract by the perimeter.
60.3 is the side lengths all together that we know
82-60.3=21.7
Hope this helped!!
Answer:
1
Step-by-step explanation:
Since DE is the perpendicular bisector of JL.
The perpendicular bisector is a line that divides a line segment into two equal parts. It also makes a right angle with the line segment. Each point on the perpendicular bisector is the same distance from each of the endpoints of the original line segment.
Since, a perpendicular bisector is a line that divides a line segment into two equal parts.
So, JK=KL. (which is not given in the option)
Since ED is a perpendicular bisector. So, each point on ED is the same distance from the endpoints of line segment JL.
So, EJ=EL.
Therefore, Option 1 is the correct answer.
