What's the issue? You gave the possible answers but that's about it.
Answer:
If C is a supplementary angle (Adds to B to equal 180 degrees), then C=180-67=113 degrees.
If C is a complementary angle (Adds to B to equal 90 degrees), then C=90-67=23 degrees.
Step-by-step explanation:
Answer:
AB = DC So ∠A and ∠D are bigger then 90%

<u>Therefore, the matrix A + 2B will be:</u>
<u>Therefore:</u>
<u>Matrix:</u> A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.
Horizontal lines are called rows and vertical lines are called columns.
<u>Order of Matrix:</u> A matrix containing x rows and y column has order x × y and it has xy elements.
<u>Different types of matrices:</u>
Row Matrix: This type of matrices have only 1 row. <u>Example:</u>
<u>Column Matrix:</u> This type of matrices have only 1 column. Example:
<u>Square Matrix:</u> In this type of matrix, number of rows and columns are equal. Example:
<u>Zero Matrix:</u> It is a matrix with all elements present is zero. Example:
<u>Identity Matrix:</u> In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:
