Answer:
B: m∠S + m∠T < m∠R.
Step-by-step explanation:
If in triangle RST, m∠R > m∠S + m∠T, then the following must be true:
A: m∠R > 90°: This is possible but not necessarily true, as m∠R could be greater than 90 degrees, but it could also be less.
B: m∠S + m∠T < m∠R: This is a restatement of the given information, so it must be true.
C: m∠S + m∠T < 90°: This follows from B, since if m∠S + m∠T < m∠R, then it must also be less than 90 degrees.
D: m∠T < m∠R: This is not necessarily true, as m∠T and m∠R could both be greater than 90 degrees.
E: m∠R > m∠S: This is possible but not necessarily true, as m∠R could be greater than m∠S, but it could also be less.
F: m∠S > m∠T: This is possible but not necessarily true, as m∠S could be greater than m∠T, but it could also be less.
So the only answer that must be true is B: m∠S + m∠T < m∠R.
