Here’s the answer: 3/2-5/2= -3. Did this help
Answer:
θ = ![30^{0}](https://tex.z-dn.net/?f=30%5E%7B0%7D)
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
Sin θ = ![\frac{800}{1600}](https://tex.z-dn.net/?f=%5Cfrac%7B800%7D%7B1600%7D)
= 0.5
θ =
0.5
θ = ![30^{0}](https://tex.z-dn.net/?f=30%5E%7B0%7D)
Thus, the angle of elevation from the base to the top of the mountain is

Answer:
-4 I guess? well I'm trying to help people
Work=speed times time (my equation to help me figure it out)
ok, 10 men take 84 days to complete a job
therefor, each man completes 1/10 of the job in 84 days
each man does 1/840 of the job per 1 day
so, if we had 5 more, or 15 men
15 times 1/840 times xdays=1 job complete
15/840 times xdays=1job
times both sides by 840/15
xdays=840/15
xdays=56
56 days it would take
