Answer the following questions, which relate to the aggregate expenditures model: LO11.8 a. If Ca is $100, Ig is $50, Xn is −$10, and G is $30, what is the economy’s equilibrium GDP? b. If real GDP in an economy is currently $200, Ca is $100, Ig is $50, Xn is −$10, and G is $30, will the economy’s real GDP rise, fall, or stay the same? c. Suppose that full-employment (and full-capacity) output in an economy is $200. If Ca is $150, Ig is $50, Xn is −$10, and G is $30, what will be the macroeconomic result? www. pdflobby.

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.
