Mathematics
1 answer:
Semmy [17]3 years ago
3 0

Answer:

BC = 6

Step-by-step explanation:

Using the sine ratio in the right triangle and exact value

sin30° = \frac{1}{2}

sin30° = \frac{opposite}{hypotenuse} = \frac{BC}{AB} = \frac{x}{12} = \frac{1}{2} ( cross- multiply )

2x = 12 ( divide both sides by 2 )

x = 6

That is BC = 6

n200080 [17]

Answer:

The volume of soil in Darren's planter box is 56 feet³

Step-by-step explanation:

The formula of the volume of a rectangular box is V = l × w × h, where l is its length , w is its width and h is its height

∵ Darren's planter box is seven feet long and four feet wide

∴ l = 7 feet

∴ w = 4 feet

<em>The volume of the soil is equal to the volume of the box using the height of the soil, because the soil takes the shape of the box, so they have the same dimensions of the base</em>

∵ Darren fills the planter box with soil to a height of two feet

∴ h = 2 feet

- Substitute the values of l, w and h in the formula of the volume

∵ V = 7 × 4 × 2

∴ V = 56 feet³

The volume of soil in Darren's planter box is 56 feet³
