data, or the facts and figures that have already been collected about Coffee Collective prior to the research at hand, might include previous years' budgets, old Coffee Collective marketing activities, internal sales figures, and customer emails.

a. derived datab. internal secondary datac. external secondary datad. external primary datae. internal primary data

b. internal secondary data

Explanation:

The internal secondary data is the data which is to be collected within the organization or internally so it could be analyzed accordingly

The data, facts and figures have already been obtained in the given scenario and are collected prior to the research on hand so that they can be called secondary internal data

Hence, the b option is correct

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.
