Answer:
The surface area of the model pyramid is
Step-by-step explanation:
we know that
The surface area of the pyramid is equal to
where
B is the area of the base of the pyramid
LA is the lateral surface of the pyramid
<em>Find the area of the base B</em>
-----> is a square
<em>Find the lateral surface area of the pyramid LA</em>
we know that
The lateral surface area is equal to the area of its four triangular faces
<em>Find the surface area of the pyramid</em>
Substitute the values
Answer:
Therefore, the length of hypotenuse is: 13 units
Step-by-step explanation:
- As the given triangle is a right triangle.
- We can find the length of hypotenuse using the Pythagoras' Theorem
Let c be the length of hypotenuse
Using Pythagoras' Theorem for the given triangle
As the length of hypotenuse cannot be negative. Therefore, the length of hypotenuse is: 13 units
Answer:
- Equal midpoints of AC and BC.
- The product of the slopes of the diagonals AC and DB is -1.
Step-by-step explanation:
1. Plot the given points, as you can see in the graph attached.
2. Calculate the midpoint of AC and DB:
Therefore, the midpoint of AC and DB are equal.
3. Calculte the slope of the diagonals AC and DB:
4. Multiply the slopes of the diagonals:
(AC and DB are perpendicular)
