Sagot :
Answer:
142°
Step-by-step explanation:
Make a line parallel to RT to create alternate internal angles
Answer:
- 142°
Step-by-step explanation:
Since QS ║ MN, the following equations are true:
- m∠SQT = m∠QNM as alternate interior angles
- m∠QNM = 180° - 72° = 108° as linear pair
The angle QSR is exterior of ΔSQT.
Exterior angle measure is the sum of non-adjacent interior angles:
- m∠QSR = m∠SQT + m∠STQ
- m∠QSR = 108° + 34° = 142°
