Answer:
with what?
Step-by-step explanation:
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:
they're equal
Step-by-step explanation:
1 liter is equal to 1,000 ml, so 5 liters is equal to 5,000 ml
You would save $15 for each week you save
Answer:
3F
Step-by-step explanation:
Force = k * x
so k = force/distance = F/2
if you were to duplicate the distance 2 times more, the F must also do so so that it's proportional
so F*2 = 2F but since it says additional 4cm, you will need to add the initial one and this one so that it's 6cm in total.
2F + F = 3F
