Can someone me with my geometry. it is how to find x?

X would be 45 degrees because we know that 45+x=90 degrees. You can tell because when both angles are put together, they make a 90 degrees angle. So, we subtract 45 from 90 to get 45 due to you needing to isolate x. Thus, the answer is 45 degrees. If you can, please mark me as brainliest.

X would be 45 because it is a right angle which is equal to 90 so 90 minus 45 is 45

Ithink it would be 1.24 pounds
