The picture below shows a pole and its shadow: A pole is shown with a right triangle side. The right triangle has hypotenuse 221 cm and base 21 cm.

What is the height of the pole?

121 centimeters
220 centimeters
225 centimeters

the  height of the pole is 220 centimeters

Step-by-step explanation:

The computation of the height of the pole is shown below

Here we applied the pythagoras theorem

Given that

Hypotenuse = 221 = c

And, base = 21 cm = b

a^2 + b^2 = c^2

So, the height is

= 21^2 cm - 221 cm

= 441 cm - 221 cm

= 220 cm

Hence, the  height of the pole is 220 centimeters

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 !
