S, T and U are inner angles in a triangle. If S= T+ U, what can't be the size of T? Choose one:
A) 960 DEGREES
B) 9770 DEGREES
C) 9570 DEGREES
D) 940 DEGREES
E) 90 DEGREES
Given S= T+ U, and S, T and U are inner angles in a triangle. Thus S+ T+ U= 180   T+ U+ T + U= 180 =&gt; 2(T+ U) = 180 =&gt; T+ U= 90. Thus beta will be less than 90.   Hence the answer is 90 DEGREES.
