The triangle it is in is equilateral (as shown by the lines through the lines) and equilateral triangles have angles of 60.
Hope this helps :)
Answer: I am not sure exctly what the question is here but if you are wondering how many butterflies tatal for all species here it is:
North American Butterfrlies: 30
South American Butterflies: 18
Europe Butterflies: 12
Step-by-step explanation: To get the total number of butterflies per species you need to mulitply to find the correct ratio given the total number of North American Butterflies is 30
North American Butterflies to South American Butterflies is 5 to 3 so 30/5=6, you then multiply 3*6 to get 18 South American Butterflies.
Then since we now know there are 18 South American Butterflies and the ratio of those to Europe Butterflies are 3 to 2 we take 18/3=6, then multiply 2*6 to get 12 Europe Butterflies.
Notice that
2010 ≡ 1 mod 2009
2011 ≡ 2 mod 2009
2012 ≡ 3 mod 2009
...
4017 ≡ 2008 mod 2009
4018 ≡ 0 mod 2009
So really, <em>S</em> is just the sum of the first 2008 positive integers:
where we invoke the formula
and so <em>S</em> ≡ 0 mod 2009.
