Answer:
D) all of the above
Step-by-step explanation:
Since, By the Pythagoras theorem,
In a right angle the sum of the square of two small sides is equal too the square of the large side.
Since,
⇒ They are measures of a right triangle.
⇒ They are measures of a right triangle.
⇒ They are measures of a right triangle.
Hence, option 'D' is correct.

24
EXPLANATION
For a matrix A of order n×n, the cofactor of element
is defined to be
is the minor of element
equal to the determinant of the matrix we get by taking matrix A and deleting row i and column j.
Here, we have
M₁₁ is the determinant of the matrix that is matrix A with row 1 and column 1 removed. The bold entries are the row and the column we delete.
Since the determinant of a 2×2 matrix is
it follows that
so
Answer:
Lateral surface area of the storage shed = 336 ft²
Step-by-step explanation:
The picture is the complete question.
The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.
lateral area of a rectangular prism = 2h (l + w)
where
l = length
h = height
w = width
h = 8 ft
l = 14 ft
w = 7 ft
lateral area of a rectangular prism = 2h (l + w)
lateral area of a rectangular prism = 2 × 8 × (14 + 7)
lateral area of a rectangular prism = 16 (21)
lateral area of a rectangular prism = 336 ft²
Lateral surface area of the storage shed = 336 ft²
