Answer:
The angle must be at 3.81°
Step-by-step explanation:
The horizontal distance of the shooting range is 60 yards
The height of the target is 12ft.
We'll have to convert the value of the height from ft to yards.
1 yards = 3 foot
X yards = 12ft
X = 4yards.
The height of the target is 4 yards.
Now, to find the angle at which the shooter makes with the zenith of the target(height), we'll have to use use SOHCAHTOA
To know which of the rules we'll follow, a pictorial illustration of the values will help
(See attached document for better illustration).
From the diagram, we can see we have values at both opposite and adjacent.
Opposite = 4
Adjacent = 60
Hence we can use Tanθ = opposite/ adjacent
Tanθ = 4 / 60
Tanθ = 0.067
θ = Tan⁻0.067
θ = 3.81°
The angle at which the rifle must be set to hit the target is 3.81°
Answer:
1st one is 0.021
2nd one is 0.009
the last question is 0.015 tho
Answer:

And we know that the value for the west side is 
So then if we solve for x from the last equation we got:

So then the east side is about
long
Step-by-step explanation:
For this problem we know that the east side of Mrs. Hammond's ranch is 455 meters longer than the west side. Let's say that the east side is x and the west is y so we have this formula:

And we know that the value for the west side is 
So then if we solve for x from the last equation we got:

So then the east side is about
long
Divide the numerator by the denominator will equal 0.625, then added to the 4 the final answer will eaqul 4.625
Your answer would have to be C; -1 1/6. Hope this Helps!!
