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.

since angle B is greater than 90; A+C<90 because sum of three angles of a traingle is 180.
so C<90-A==> C<65. options A,B,C,D satisfy this condition.

Third angle < 180-(25+90)
Third angel < 65

Answer: A B C D
