An oil company in the United States develops an advertisement that promotes offshore oil-drilling in the country. The ad states the availability of oil resources and stresses the importance of reducing dependence on foreign oil sources. The ad's goal is to get members of the public to support offshore drilling. This is an example of?

advocacy advertising.

Explanation:

An oil company in the United States develops an advertisement that promotes offshore oil-drilling in the country. The ad states the availability of oil resources and stresses the importance of reducing dependence on foreign oil sources. The ad's goal is to get members of the public to support offshore drilling. This is an example of advocacy advertising.

The older generations see the natural Alaskan setting as central to their culture and identity. The younger natives support the oil drilling because it will provide valuable jobs and bolster the economy.

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 a.
