She had to make a 90 flat
hope this helps (;
C would = 5 to make this statement true
Answer:
option D
2x4; -11
Step-by-step explanation:
Order of matrix is in form (m x n), here m is the row and n is the column of the matrix.
So this matrix have 2 rows and 4 columns
1)Order of matrix
2x4
2)
here 1 is the row and 2 is the column
-11
Each elements of the matrix can be identity as below
![\left[\begin{array}{cccc}x_{11} &x_{12} &x_{13} &x_{14} \\x_{21} &x_{22} &x_{23} &x_{24} \\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7Dx_%7B11%7D%20%26x_%7B12%7D%20%26x_%7B13%7D%20%26x_%7B14%7D%20%5C%5Cx_%7B21%7D%20%26x_%7B22%7D%20%26x_%7B23%7D%20%26x_%7B24%7D%20%5C%5C%5Cend%7Barray%7D%5Cright%5D)
This is a rhombus and in any rhombus, the diagonals intersects in the middle and they are perpendicular:
So all 4 triangles are right triangles and the sides are the hypotenuses.
1st) Calculate the sides: hypotenuse² = 3² + 4² = 25, and hypotenuse = 5
The area of each right triangle is (4 x 3)/2 = 6 units²
And the area of the 4 right triangles = 4 x 6 = 24 init²
