Chinook industries inc. is evaluating two capital investment proposals for a retail outlet, each requiring an investment of $900,000 and each with an eight-year life and expected total net cash flows of $1,000,000. location 1 is expected to provide equal annual net cash flows of $200,000, and location 2 is expected to have the following unequal annual net cash flows: year 1 $300,000 year 5 $50,000 year 2 220,000 year 6 50,000 year 3 180,000 year 7 30,000 year 4 150,000 year 8 20,000 determine the cash payback period for both location proposals. location 1 location

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.
