Construct a ?XYZ in which YZ=4.2 cm angle Y=120 degree and XY=3.9 cm. Draw XP perpendicular ZY( produced if required)

Dear Student,
Here is your solution.

1.Draw YZ=4.2 cm
2.With Y draw angle 120 degree.
3. Mark point X at distance of 3.9 cm
4.Angle XYZ = 120 degree then foot of perpendicular from X to YZ lies externally. Extend ZY.
5. Take a arc on extended ZY cut at A and B
6.Draw perpendicular bisector of AB which also pass through X and cut YZ  at P.
