We have to find the included angle between [tex] \overline{JL} [/tex] and [tex] \overline{JK} [/tex].
An angle is the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
Here, in the given triangle KLJ, Angles formed along the line segment JL are [tex] \angle J [/tex] and [tex] \angle L [/tex].
Angles formed along the line segment JK are [tex] \angle J [/tex] and [tex] \angle K [/tex].
So, the included angle between the line segments JL and JK is [tex] \angle J [/tex].
