<h2>Answer:</h2>
This problem can be solved using trigonomtry, assuming that the figure formed by Adam's shadow and Adam himself is a Right Triangle (as shown in the figure attached).
According to this, the distance from the tip of the shadow to the top of Adam's head is the hypotenuse of the triangle, and we already know Adam's height and the angle of elevation. So, the trigonometric function that best works in this case is sine:
Where the opposite leg is the side of the triangle that is opposite to the angle.
In this especific case:
(1)
In order to know the value of the hypotenuse we have to find from equation (1):
Rounding:
