22 x 2 is 44 plus 100 is 144
Answer:
The answer is sin-1(5/8)
Step-by-step explanation:
I don't have a calculator but just plug that in in degree mode.
For any arbitrary 2x2 matrices

and

, only one choice of

exists to satisfy

, which is the identity matrix.
There is no other matrix that would work unless we place some more restrictions on

. One such restriction would be to ensure that

is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking

we'd get equality.
