Why is the hospitality industry considered diverse and complex?

Because the clients and the employees are diverse and because there are major groups of hotels chains that dominate the industry.

Explanation:

To begin with, the hospitality industry is considered to be so diverse because of the wide range of clients that is it has, representing people from all over the world, the consumers of the hospitality industry tend to have very different cultures, languages, ethics and more and that is becuase the whole world is to be considered a client when it comes to this industry. Moreover, the workers of the industry tend to be from different places as well because that gives a plus to the company who receives people from everywhere.

Secondly, this industry it is considered to be complex due to the fact that most of the hotels chains are the ones that dominate the industry and therefore that one group of hotels is the one that receives the most of the clients and so on.  

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.
