Answer:
Explanation: The United States of America and Canada have one of the worlds oldest environmental partnerships. The various ways they're partnering to better the environment include:
1. The U.S. - Canada Air Quality Agreement.
This Agreement was signed in 1991 with the aim of working towards the reduction of air emissions which cause cause acid rain. The Agreement was later expanded in the year 2000 with the goal of reducing transboundary smog emissions under the Ozone Annex.
2. The Great Lakes Water Quality Agreement.
This Agreement was initially signed in 1972, and amended in 2012. The goal of the Agreement is to provide a mechanism that involves the effort and cooperation of both countries, that will be geared toward the protection of the Great Lakes Basin ecosystem.
<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:
>>>>>This is the distance from the tip of the shadow to the top of Adam's head
