Correct Question:
If OQ and RT are parallel lines and QPS= 77°, what is TSU?
Answer:
77°
Explanation:
Since OQ and RT are parallel to each other, and, <TSU and QPS are corresponding angles lying on the same side of the transversal as well as being positioned in the same corner, therefore:
<TSU is congruent to <QPS.
Thus:
m<TSU = m<QPS
m<TSU = 77° (substitution).
