In the early 1970s, inflation was hitting the U. S. economy, and one of the results was that beef prices began to rise to record levels. Some of President Richard Nixon's advisers urged him to place price controls on the sale of beef cattle with the intended purpose being to hold down the price of cattle. If cattle prices were kept from rising, the advisers reasoned, then beef prices also would not rise. (The president did not follow their recommendations, but he did place overall wage and price controls on the economy for a while.) Had the president implemented this recommendation of price controls on beef cattle, would that action have resulted in lower beef prices

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.
