The valence electrons (outer shell electrons) get shared between the first and second element in the compound the purpose is for both the elements to get to the stable state by having the outer shell filled up to 8 electrons. See image.
Answer: The length of the ladder is 20 feet.
Step-by-step explanation:
Given : A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 8 feet less than the length of the ladder.
Mathematically,
Let x be the length of the ladder then
Distance from ground to the top of the ladder = x- 8
If distance from the bottom of the ladder to the building is 16 feet.
Since ground makes right angle with building , so the triangle made by ladder should be a right triangle.
By Pythagoras theorem of right triangle , we hae
Hence, the length of the ladder is 20 feet.
