An auditor most likely will review an entity's periodic accounting for the numerical sequence of shipping documents and invoices to support management's financial statement assertion ofa. occurrenceb. rights and obligationsc. valuation and allocationd. completeness

 C - Valuation & Allocation

Explanation: Auditors review of a company's shipping documents & invoices is to ascertain the correctness of the figures in the financial statement.

Auditors will have to value the transaction using the invoices and other documents available for the transaction and to to verify that the costs are allocated correctly.

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.

the answer is d
