Answer:
(x+2) (x+1)
Step-by-step explanation:
Answer:
x=0.4, x=-1.2
Step-by-step explanation:
Treat it like a fraction
18b^2/45b
divide top and bottom by b
18b/45
divide top and bottom by 3
6b/15
divide top and bottom by 3 again
2b/5
2b:5 is the simpliest form of the ratio
So I didn’t read the whole thing but 20 is b.
We can use trigonometry to solve the problem. First draw a picture of the situation to understand what is going on (See the attached photo).
Next, we can use the tangent function to solve for the height of the building:
Next, rearrange the problem to solve for h:
h = 39.356 ft
