Please help me solve this.... the answer is going to be "not possible" or "undefined" etc.
But I'm not sure how...
Because Inverse of cosine's domain is greater than or equal to -1 and less than or equal to 1
So, inverse cosine of -1/4 is okay
Since the range is restricted to 0degrees to 180 degrees, it would have to be in quadrant 2 (where x is negative)
So i'm all good there.... and I would think I'm good to do tan of whatever that angle is, but then i get error on calculator which means undefined
PLEASE help
