In triangle δabc, ∠c is a right angle and cd is the height to
ab. find the angles in δcbd and δcad if:

m∠a = α

m∠cdb =

m∠cbd =

m∠bcd =

m∠cda =

m∠cad=

m∠acd =

Step-by-step explanation:

The triangles are drawn below.

CD is perpendicular to AB as CD is height to AB.

Therefore, angles °

So, triangles ΔCBD and ΔCAD are right angled triangles.

Now, from the right angled triangle ΔABC,

From ΔCBD,

is same as .

So,

Now, from ΔCAD,

is same as

So,

Hence, the unknown angles of both the triangles are:

0.02040816326

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 !
