Answer:
x is approximately 226.3 feet
y is approximately 308.6 feet
z is approximately 226.3 feet
Step-by-step explanation:
The given parameters of the walls are;
The angle of elevation from the top of the shorter wall to the top of the opposing wall, θ₁ = 20°
From the diagram, the angle of depression from the top of the shorter wall to the bottom of the opposing wall, θ₂ = 45°
The distance from the bottom of the shorter wall to the base of the opposing wall, l = 320 feet
x = The height of the shorter wall = l × sin(θ₂)
∴ x = 320 feet × sin(45°) = 320 feet × (√2)/2 = 160·√2 feet ≈ 226.3 feet
∴ x ≈ 226.3 feet
By observation, we have;
y = x + z × tan(θ₁)
Where;
z = l × cos(θ₂)
∴ y = 160·√2 + 320 × cos(45°) × tan(20°) ≈ 308.6
y ≈ 308.6 feet
z = l × cos(θ₂)
∴ z = 320 × cos(45°) = 160·√2 ≈ 226.3
z ≈ 226.3 feet.
Answer:
x = 
Step-by-step explanation:
2x – 4 – (x + 2) = 6x is the given equation
Now simplifying both sides, we get
2x - 4 - x - 2 = 6x
taking like terms on each side of the equality, we get
2x - x - 6x = 4 + 2
or, -5x = 6
or x = 
hence, the value of x =

Answer:
Tamiko will save 86.25
Step-by-step explanation:
Tamiko's earning from fast food restaurant check = 109.60
Tamiko's earning from small bonus check = 34.15
net amount earned by Tamiko = Tamiko's earning from fast food restaurant check + Tamiko's earning from small bonus check
net amount earned by Tamiko = 143.75
As she wants to save
of the net amount.
the amount saved = 
=
