Monique and zhong worked at the same company for five years without knowing much about each other. one day, at a company party, they began talking and really hit it off. they have been dating ever since. how did zhong and monique's relationship transform over time?

The answer to the question relates to the concept of primary and secondary group. Primary group is a small social group where members share personal relationships that are generally enduring while secondary groups are large groups where relationships are temporary, impersonal, and goal-oriented.  

The relationship between Monique and Zhong start off as members of a secondary group, which is their company. When they met in a company party and eventually dated each other, they become members of a primary group, which is a couple.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.

hi there,

do u need ? ?

thx
