Dean is 75 years old and is covered by Medicare. In 2019 he had spinal fusion surgery to correct problems caused by three ruptured disks and was transferred to a skilled nursing care facility for rehabilitation after recovery in the hospital. If Dean remained in the skilled nursing facility for 30 days, how much will he have to pay as a coinsurance amount? a. $0.
b. $1,705.
c. $3,350.
d. $5,025.

answer; i believe the correct answer is (treasury bills);

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.
