Answer:
x = (-5/2)
Step-by-step explanation:
4 - (2x + 4) = 5
-4 from both sides
- (2x + 4) = 1
divide both sides by -1
2x + 4 = -1
-4 from both sides
2x = -5
divide both sides by 2
x = (-5/2)
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°
Add y subtract 6. Ur left with y=x-6
Add the equations and ur left with 2x-10
