Explanation

SUPPLY a number for angle B. Since B > 90°, B can be anything greater than 90° (like 90.0009°), but start with the lowest possible integer, B = 91° to make calculations easier:



A + B + C = 180°
25° + 91° + C =180°
C = 64°

Now imagine if B were at the other extreme—as large as possible. :



A + B + C = 180°
25° + B + C =180°
B + C =155°
If B = 154°, then C = 1°

Angle C can be anything less than 65 degrees, so the first four answers are possible values of C.

Hence options A, B, C and D are correct.
