Geometry ! this is my last try! the two triangles below are similar. what is the similarity ratio of δabc to δdef?
a 3: 1
b 1: 3
c 2: 1
d 1: 2

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
