Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.
The answer is B
Since you know that BOD is a right angle add 12 And 15 and subtract your answer from 90
When I do this the 0.38 per one bagel is rounded
D because your x value is 6
