Which of the following is a factor to be considered in determining a limited-life intangible asset's useful life? (a)any legal provisions that may limit the useful life.(b)the expected useful life of any related asset.(c)the effects of obsolescence.(d)all of the answer choices are correct.

All of the answer choices are correct.

The following is a factor to be considered in determining a limited-life intangible asset's useful life:

(a)Any legal provisions that may limit the useful life.

(b)The expected useful life of any related asset.

(c)The effects of obsolescence.

It necessary to note that while evaluating  a limited life intangible asset the following factors are considered. i.e. legal provisions,  effects of obsolescence and etc.

Therefore, in this case the correct option is (d)

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.
