Not enough information.

Is it right angled? Is there an angle given?

The angle A could be from 0 to 180 degrees.

Insufficient information for finding a unique solution. AB can be any length in the interval (5, 25) and angle A will be different for each different length.

BC would be the opposite side (opposing the angle), BC would be the adjacent. the ratio of Opposite/ adjacent would be the tangent of the Angle. In this problem the tangent of angle A is 15/10 = 1.5. On the tangent chart, a 57 degree angle has a tangent of 1.54. A 56 degree angle has a tangent of 1.483. So the Angle is between 56 and 57 degrees. If you don't extrapolate to a more exact answer. I'd say the answer was Angel A is a 57 degree angle.

You seem to be assuming a *right* triangle.

Well, BC is the side opposite angle A.....

AC is the side opposite B

and AB is the side opposite C.....

So, more info is required

It can't be determined from the information given. You have only provided two sides. We would need either the third side, or another angle. That other angle could be 90°, for example if you had stated this was a *right* triangle, but you didn't.

Insufficient information
