Each day, you are faced with choices. you have to decide how to use your resources. for example, should you use some of your allowance money to buy new clothes? or should you save your money toward buying a computer? there are costs and benefits for each decision. governments are also faced with decisions, such as whether or not to use price controls. you already know about the costs and benefits of a specific price control called rent control. in this project, you will assess rent control while playing the role of a minimum wage earner.

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.
