Answer questions 11 and 12
really urgenttt

11.) 135°   12.) 45°

Step-by-step explanation:

11.) When finding one interior angle, you will have to first find the sum of the interior angle using the formula:

Sum of interior angle = ( n - 2 ) 180° where "n" is the number of sides of that shape. So the working will be:

( 8 - 2 ) 180°

= 6 x 180°

Sum of interior angle = 1080°

To find the angle of one interior angle, divide it by the number of sides of that shape.

1080° ÷ 8 = 135°

∴ The measure of one interior angle is 135°

12.) To find the exterior angle, use the formula:

Exterior angle = 360° ÷ n where "n" is the number of sides of that shape. So the working will be:

360° ÷ 8 = 45°

∴ The measure of one exterior angle is 45°

Extra: You can check if the answer is correct by multiplying the answer you got for the exterior angle with the number of sides and that should give you 360°.

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 !
