Not enough information.

Is it right angled? Is there an angle given?

• The angle A could be from 0 to 180 degrees. • Log in to reply to the answers
• 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.....
