The perimeter of a triangle is 69 cm. the first is 5 cm shorter than the second side. the third side is twice as long the first side. find the length of each side

Side a = 23 Side b = 28  Side c =46

Step-by-step explanation:

First set up your equation witch is x-5+x+x-5*2=69

Then Simplify x+-5+x+x+-10=69

Then combine like terms 3x-15=69

Add 15 to both sides

After you will get 3x=84

then divide both sides by 3

You will get x=28

Then go back to your question it says THE FIRST IS 5 CM SHORTER THAN THE SECOND SIDE. THE THIRD SIDE IS TWICE AS LONG AS THE FIRST SIDE. So that tells you that to find A, you do 28-5=23, to side b is x so its 28, and to find side c you do 28-5*2=46. So A=23, B=28, and C=46.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

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 !
