Answer:
x = 7
Step-by-step explanation:
the 2 is doubled so the 3.5 has to be doubled as well
C. the original answer is t<3, but that is not a choice on there soooo, it is C. it has the answer, and its close enough.
i hope this helps.

Answer:
angle of elevation will be ![2.14^o.](https://tex.z-dn.net/?f=2.14%5Eo.)
Step-by-step explanation:
Given,
height of tower = 150 ft
height of tower = 1200 ft
So, total height of peak of tower = 1200 + 150
= 1350 ft
distance of user from cell tower = 5 miles
= 5 x 5280 feet
= 26,400 feet
Since the height of user from sea level = 400 ft
so, height of peak of tower with respect to user = 1350 - 400 ft
= 950 ft
If the angle of depression is assumed as
, then we can write
![tan\theta\ =\ \dfrac{\textrm{height of peak of tower w.r.t user}}{\textrm{distance of user from tower}}](https://tex.z-dn.net/?f=tan%5Ctheta%5C%20%3D%5C%20%5Cdfrac%7B%5Ctextrm%7Bheight%20of%20peak%20of%20tower%20w.r.t%20user%7D%7D%7B%5Ctextrm%7Bdistance%20of%20user%20from%20tower%7D%7D)
![=>\ tan\theta\ =\ \dfrac{950}{26400}](https://tex.z-dn.net/?f=%3D%3E%5C%20tan%5Ctheta%5C%20%3D%5C%20%5Cdfrac%7B950%7D%7B26400%7D)
![=>\ tan\theta\ =\ 0.374](https://tex.z-dn.net/?f=%3D%3E%5C%20tan%5Ctheta%5C%20%3D%5C%200.374)
![=>\ \theta\ =\ 2.14^o](https://tex.z-dn.net/?f=%3D%3E%5C%20%5Ctheta%5C%20%3D%5C%202.14%5Eo)
So, the angle of elevation will be ![2.14^o.](https://tex.z-dn.net/?f=2.14%5Eo.)
Answer:
Answer to A: 12 minutes
Answer to B: 36 minutes
Answer to C: Naomi runs faster because 4 times 2 is 8, so it takes her 8 minutes to run a mile.
