The given in this problem implies a contradiction.
Note that so .
But which impossible as the hypotenuse is 5.
So review the question. It is faulty as given.
I'm sorry you're right
I was able to solve it once I understood the whole base was 4-x not just that piece
I was able to get x = -1 and angle A is 101.5
x is negative because it goes to the left of the coords into negatives
The problem was badly written, it is solved now
