Answer:
In the pic
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below =)
since we don't know any of your vocabulary, I might not be using the ones you learned
since we have points A and B and points F(A) and F(B), I think they want us to use the word 'translation'
"The function F(x) translates each point to the right without moving them up or down." would be my description
also the 2 lines are paralell
For this case, what we must do is solve the following system of equations:
tan (50) = h / x
tan (40) = h / (x + 50)
Solving the system we have:
(x + 50) * tan (40) = h
(x) * tan (50) = h
Matching:
(x + 50) * tan (40) = (x) * tan (50)
Rewriting:
x (tan (50) - tan (40)) = 50 * tan (40)
x = 50 * tan (40) / (tan (50) - tan (40))
x = 118.9692621
Substituting:
h = (x) * tan (50)
h = (118.9692621) * tan (50)
h = 141.7820455
Answer:
The height of the building is:
h = 141.7820455 ft
220 x 440 = 96800
96800/1000=96.8
but you can't have .8 of a bag so round in up to 97 bags
I hope this helps!
