Six:
1. Upper Mississippi
2. Arkanas River
3. Illinois River
4. Missouri River
5. Ohio River.
6. Red River
A triangle is equal to 180 degrees. we know that one of the angles is 118 and the other is 30 degrees. now we have a total of 148 degrees. so that means the other angle is 32 degrees. and both triangles are identical so that means
x= 32
so what i did you get 148 is i added 118 and 30 together and then i subtracted 118 from 180 to get 32
i hope this helps
Subtract 6.5 from 2.76 which equals -3.14 then you want to multiply -8 to -3.14. X=29.92
Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
