Answer: 59.04
Step-by-step explanation:
tan 16= x/200
tan16/1=x/200
200 tan 16=x
x=57.349077...
x=57.349077...
Add 1.69, the distance from the ground to her eye:
57.349077...+1.69=
59.039077...
≈ The skyscraper is 59.04 meters tall.
The common ratio (R) is -3.
-2 times -3 is 6.
6 times -3 is -18.
-18 times -3 is 54.
R=-3.
This is a geometric sequence.
Answer:
B and R
I think that is the name of the lines. If not the the first two lines!!!!
