I don't think you can find x in this case. Cosine can only go as low as -1 and as high as 1. Since 2.3 is more than 1, the answer does not exist
The answer is the third one: (0,-3),(4,1)
plug in the X and Y in the given equation
(0,-3): -3 = 0 - 3. this is correct
(4,1): 1 = 4-3. this is also correct
25 because you do 19 squared plus 16 squared equals 617, you do 617 rooted. It’s called pythagorus.
