For the first picture, x = 126 and therefore x - 30 = 96

Second picture:

Step-by-step explanation:

since the sum of the angles is 540°, we can say that

x + x + (x - 30) + (x - 30) + (x - 30) = 540

5x - 90 = 540

5x = 630

x = 126

therefore x - 30 = 96°

2nd picture

we use the same method as we did in the first picture:

5x + 2x + 110 = 180

7x + 110 = 180

7x = 70

x = 10, 5x = 50, 2x = 20

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

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 !
