Write and solve an equation of ratios:
9 ft 22 ft
------- = -----------
h 99 ft
This is appropriate because h is greater than 9 ft.
cross-multiplying, we get
9(99) ft^2 = 22*h*ft
Then h =40.5 ft (which is the height of the building)

Answer:
BC = 16 +12√3
Step-by-step explanation:
In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.
EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.
The length BC is ...
BC = EC +BE
BC = 16 +12√3
Answer:
D. 21
Step-by-step explanation:
28-21=7
28-7=21
Answer:
D. -6
Step-by-step explanation:
SInce x is negative, the - before the six would be cancelled out leaving the equation to be 6^3=216 which is correct
