Answer:
<h2>3m</h2>Step-by-step explanation:
Volume of a pyramid = 1/3 * Base area * height
If the top of the monument is 11m tall, then the height of the pyramid is 11m. If it will take C of bronze to make the top that is 11 m tall, the volume of the pyramid is 22m³.
Substituting the given data into the formula to get the base area;
Since the base of the pyramid is rectangular in nature,
Base Area = Length * Breadth
Base Area = 6m², and the length of the base is given as 2m, the missing dimension will be the breadth of the rectangle.
6 = 2 * Breadth
Breadth = 6/2
Breadth = 3m
The missing dimension is 3m

The width of the rectangle is unit
Step-by-step explanation:
The given is:
- A rectangles width is 4 less than its area
- Its length is 19 units
We need to find the width of the rectangle
Assume that the width of the rectangle is x units
∵ The area of the rectangle = length × width
∵ The width of the rectangle = x units
∵ The length of the rectangle = 19 units
∴ The area of the square = 19 × x = 19 x units²
∵ The width of the rectangle is 4 less than its area
- That means subtract 4 from the area to find the width
∴ x = 19 x - 4
- Subtract 19 x from both sides
∴ -18 x = -4
- Divide both sides by -18
∴ x =
- Reduce the fraction by dividing up and down by -2
∴ x =

Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)
