Answer:

the height above the ground where the board makes contact with the wall equals 5.297 meters above ground.

Step-by-step explanation:

The wall and ladder are shown in the attached figure

In the figure we can see that


cos(28^(o))=(H)/(L)\\\\cos(28^(o))=(H)/(6)\\\\\therefore H=6.0* cos(28^(o))==5.297meters
