The value of NP in the diagram is 11 units
Congruent triangles are triangles with equal side length and equal corresponding angles. The side length of congruent triangles must be equal.
The diagram above consist of three congruent triangles.
Since point M is a bisector of line JL and N is a bisector of JK, this means that;
MN = 1/2( LK)
MN = LP = PK
and
NP = 1/2( JL)
therefore
NP = ML = JM
NP = 11 units
Therefore, The value of NP in the diagram is 11units
