Answer:

Option B - Angle PTR and angle PTS are supplementary angles

Step-by-step explanation:

we know that

m∠PTR=m∠STQ -----> by vertical angles

we have that

The sum of angles PTR and PTS is always equal to 180 degrees, because are supplementary angles

so

m∠PTR+m∠PTS=180° ------> by supplementary angles
