Answer:
A Joint.
Explanation: I took the quiz.
<span>The answer is a democracy. In Greek, demos means people, so democracy (or demo.kratia in Greek) means "rule by the people". This form of government dates from about 500 years B.C. when the Athenian leader Cleisthe.nes introduced it. This form of government comprised of three separate institutions: the ekk.lesia, the bou.le, and the d.ikasteria.</span>
This is called species richness
Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35
So the 2 angles are 20 and 35 degrees.
To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)
