<span>The precambrian period was a time period that happened billions of years ago. Actually, 4.6 billion years, to be exact. The Earth started to form during this period. Layers of rock, elements of the land and waters, and many other things were developed during this time. The atmosphere had a mind of its own, per se, during this time period. It went through many different changes. The atmosphere went from being extremely cold and galactic to warming and having volcanoes, which allowed for an expansion of life forms.</span>
Answer:
Explanation:
Khyber Pass, Khyber also spelled Khaybar, orKhaibar, most northerly and important of the passes between Afghanistan and Pakistan. The pass connects Kābul with Peshāwar. The pass has historically been the gateway for invasions of the Indian subcontinent from the northwest. The name Khyber is also applied to the range of arid, broken hills through which the pass runs and which form the last spurs of the Spin Ghar (Safīd Kūh) Range. On either side of the connecting ridge are the sources of two small streams, the beds of which form the Khyber gorge. This narrow gorge forms the Khyber Pass; it winds between cliffs of shale and limestone, 600–1,000 feet (180–300 m) high, and enters the Khyber Hills from the Shadi Bagiār opening, a few miles beyond Jamrūd, Pak., and continues northwestward for about 33 miles (53 km). Just beyond the old Afghan fort of Haft Chāh, it opens onto the barren Lowyah Dakkah plain, which stretches to the Kābul River.
The Northwest Passage is a sea route that connects the Atlantic and Pacific Oceans through the Canadian Arctic Archipelago. In the past, the Northwest Passage has been virtually impassable because it was covered by thick, year-round sea ice.
<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
