Solve for x in the diagram below. 15 points :3
1 answer:
Answer: x = 6
Step-by-step explanation:
We know that the angles combined are complementary, meaning they add up to 90 degrees.
Therefore, we can make this equation:
(x + 54) + 5x = 90
Then, combine like terms.
x + 54 + 5x = 90
6x + 54 = 90
Now, subtract the 54 from that side.
6x = 90 - 54
6x = 36
Next, divide!
=
x = 6

Order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.
<h3>What is a matrix?</h3>- A matrix is a rectangular array or table of numbers, symbols, or expressions that are organized in rows and columns to represent a mathematical object or an attribute of such an object in mathematics.
- For instance, consider a matrix with two rows and three columns.
To find the order of matrix:
- We must first check the dimension of two matrices, say matrix A by matrix B, before we may multiply them.
- Multiplication is achievable if the number of columns in the first matrix, A, equals the number of rows in the second matrix.
- Dimension is assigned to the provided matrix: 6 × 5
- This means the given matrix contains six rows and five columns.
- As a result, the second matrix MUST have 5 rows in order for multiplication to be POSSIBLE.
- The only matrix with 5 rows among the above alternatives is the matrix with dimension (B) 5 × 6.
To prove:
- In other words, the inner products of the dimensions should be equal.
- That is; (a × b)(b × a) is possible but (a ×b)(c × b) is impossible.
- The dimensions of the matrix are given by, row × column.
Therefore, order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.
