A triangular-shaped deck has one side that is 4 feet longer than the shortest side and a third side that is 4 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 80 feet, what are the lengths of the three sides?

The length of three sides of the triangle are 20 feet, 24 feet  and 36 feet

Given :

Let 'x' be the shortest side of the triangle

one side that is 4 feet longer than the shortest side

so one side is 4 feet more than the shorter side

x+4

a third side that is 4 feet shorter than twice the length of the shortest side

third side is

Perimeter of the triangle is sum of all the three sides

Perimeter = x + (x+4)+(2x-4)

Given perimeter is 80 feet

The shortest side is 20 feet

One side is x+4= 20+4=24 feet

Largest side =

The length of three sides are 20 feet, 24 feet  and 36 feet

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

Step-by-step explanation:

Assuming that the shortest side of this triangle has a length of "x" feet, then one side is "x + 4" feet and the third is "2*x - 4" feet. Since the perimeter of the deck is 80 feet, then the sum of the length of these sides should be equal to that.

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

the correct answer is $7.38
