One source of leads is , which is where a salesperson tried to generate leads by calling on totally unfamiliar organizations. A. Endless chain B. Sales letters C. Networking D. Cold calling E. Spotting

D. Cold calling

Explanation:

Cold calling is the principal source for lead generation. Through that, it makes us understand the consumer requirement so we can sell our product by understanding the customer's requirements. It is the way our goods and services are distributed.

Hence, the salesperson or customer representative from Cold calling supports consumers and seeks to figure out the consumer's needs.

a

explanation:

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.
