Calculation

Expanding through R₃ we get

Independent of

Also,

Therefore,

at

Hence option 2 and 4 are correct

The correct option is: 90 

Explanation: We start with the matrix ( A ) and the given equation ( A + A^T - 2I = 0 ).

Given:

• First, determine the transpose of ( A ):
• Next, add ( A ) and ( A^T ): [ A + A^T =
• Now, subtract ( 2I ) from ( A + A^T ):
• Set ( A + A^T - 2I ) equal to the zero matrix:
• This results in the following equations:
• Solving these gives:
• The only angle that satisfies both equations is

Thus, the value of (θ) is 90.
