Answer:

The  length is  D  =  5 \ cm

Explanation:

From the question we are told  that

     The  length of the  hand is  l  =  10.0 \ cm

      The  angle at the hand is  held is  \theta  =  30 ^o

Generally resolving the length the length of the hand to it vertical component we obtain that the length of the shadow on the vertical wall is mathematically evaluated as

             D  =  l * sin(\theta )

substituting values

             D  =  10 * sin (30)

             D  =  5 \ cm
